Array Functions
You can use the Array functions to summarize field data in several different ways.
When using the Array functions, if you assign a field_variable to a variable, for example "X", the variable "X" loses the characteristic of representing a group of values. The following formula are then incorrect.
Number x = @dbfield;
Number y = Average(x); // system will prompt you that there is no such kind of function.Number x = @dbfield;
Number y = Variance(x); // system will prompt you that there is no such kind of function.

Date/Time Functions
Date/Time functions enable you to convert numbers to dates and dates to numbers.
| Function | Description | Parameter | Return Value | Example | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| CurrentDate() | This function returns the current date on a report. | A Date value. | If today is Oct. 6,1999, the return value of the following statement is "10/06/99".
| ||||||||||||||||
| CurrentDateTime() | This function returns the current date and time on a report. | A DateTime value. | If today is Oct.6,1999, the current time is 5:10:27 p.m., the return value of the following statement is "1999-10-06 05:10:27 PM".
| ||||||||||||||||
| CurrentTime() | This function returns the current time on a report. | A Time value. | If the current time is 5:10:27 p.m., the return value of the following statement is "05:10:27 PM".
| ||||||||||||||||
| DateAdd(intervalType, nIntervals, startDateTime) | This function returns a DateTime value to which a specified number of time intervals have been added. You can use this function to add interval of time to a DateTime. Its main feature is that the DateTime returned is always valid. For example, the function takes into account such factors as the number of days in a month and leap years. If you want to add or subtract days to a DateTime, you could use the addition and subtraction operators instead of the function with the "d" parameter. However, this function also handles other types of intervals such as adding months or hours to a DateTime. |
Notes:
| A DateTime value. |
| |||||||||||||||
| DateDiff(intervalType, startDateTime, endDateTime, firstDayOfWeek)
Overloads:
| This function returns a number of time intervals between two specified dates. |
| A Number value. |
The following examples use DateDiff with the "YYYY" interval type parameter to find the number of years difference between two dates. This use of DateDiff is the same as finding the difference between the year of endDateTime and the year of startDateTime.
Suppose that for the above examples, the first date is the date that you bought a mutual fund, and the second date is the date you sold it. The mutual fund company must send you an annual report for every year in which you owned units in the fund. You would then get 7, 2, and 1 annual reports respectively, in the above cases. The following examples use DateDiff with the "Q" parameter to find the number of quarters (3 month periods) difference between two dates.
Suppose the mutual fund company in the "YYYY" example mailed out quarterly reports. It would need to mail out 15, 2, and 1 quarterly reports respectively, in the above cases.
The following examples use DateDiff with the "W" parameter to calculate the number of weeks between two dates. For example, if startDateTime is on a Tuesday, DateDiff counts the number of Tuesdays between startDateTime and endDateTime, not including the initial Tuesday of startDateTime. Note however that it counts endDateTime if it is on a Tuesday.

| FV(rate, periods, payment, presentMoney, type)
Overloads:
| This function returns a number specifying the future value of an annuity based on periodic, fixed payments and a fixed interest rate. |
| A Number value. | Suppose that you put $1100 per month into a retirement savings plan that pays 6 percent annual interest, compounded monthly. How much will the account be worth after 20 years? The following example assumes that you make your payments into the plan at the end of the month. Thus, after the first month, your plan would have $1100 in it, since there wouldn't have been enough time for any interest to accrue.
Suppose that instead, you make your payments at the start of the month:
Now suppose that in addition to making payments at the start of the month, you start your plan with an initial deposit of $25,000:
You can also use the FV function to calculate the future value of a lump sum deposit. For example, if you deposit $25,000 into a plan that pays 6 percent annual interest compounded monthly for 20 years:

The following formula returns the amount of interest that you pay in your 97th payment (after 10 years of payments):
|
| IRR(values, guess)
Overloads:
| This function returns a number specifying the internal rate of return for a series of periodic cash flows (payments and receipts). |
| A Number value. | Suppose that you can choose one of two offers: $20,000 now or guaranteed payments of $5,000 after one year, $10,000 after two years and $15,000 after three years. Which is the better offer? One way to quantify this is to calculate the internal rate of return. If you take the second offer, you cannot take the first, which is like experiencing an initial payment of $20,000 followed by the receipts:
Returns "0.201" (rounded to 3 decimals) or "20.1 percent" interest. With all other things being equal, if you think that 20.1 percent is a good rate of return, you would prefer the second offer. |
| MIRR(valueArray, financeRate, reinvestRate) | This function returns a number specifying the modified internal rate of return for a series of periodic cash flows (payments and receipts). |
| A Number value. | Suppose that you run a business that makes equipment investments, which results in a loss in the first and fourth years.

The modified internal rate of return is:
|
| NPer(rate, payment, presentMoney, futureMoney, type)
Overloads:
| This function returns a number specifying the number of periods for an annuity based on periodic, fixed payments and a fixed interest rate. |
| A Number value. | Suppose that you want a $250,000 loan to buy a house. The interest rate is 6.5 percent and you can afford to pay $3,000 per month. How long a mortgage would you need?
Rather than seeking a loan, suppose that you want to save $500,000 and then buy the house. You can get a 6.5 percent interest rate compounded monthly from your savings plan, and you want to save $3,000 per month. How long would you need to save before you had the required amount of money?
|
| NPV(rate, values) | This function returns a number specifying the net present value of an investment based on a series of periodic cash flows (payments and receipts) and a discount rate. |
| A Number value. | Suppose that someone offers to pay you $15000 after one year, $20000 after two years, $25000 after three years, and $12000 after four years. If the discount rate (the Time value of money) is 6.5 percent, the value of this offer to you today is:
The formula returns "61741.8". So this scheme is worth $61,741.8 to you today. This is less than the sum of the payments, which is $72000, since you have to wait for this money. |
| Pmt(rate, periods, presentMoney, futureMoney, type)
Overloads:
| This function returns a number specifying the payment for an annuity based on periodic, fixed payments, and a fixed interest rate. To find the total amount paid out over the whole loan, multiply the payment per period (the value returned by Pmt) by the total number of periods. |
| A Number value. | Suppose that you want to take out a $250,000 loan payable monthly over 15 years at an annual interest rate of 6.5 percent. The following formula returns your monthly loan payment. Note that the monthly interest rate is 0.065 / 12, and the number of months of the loan is 15 * 12.
Now suppose that the payments are made at the beginning of the month instead of the end (default). Your monthly loan payment is calculated as:
Now suppose that you know that you'll receive $80,000 in 15 years. In this case, there is no need to fully pay off the loan. You only need to reduce the amount owed to $80,000 after 15 years. Note that the future value is negative since after 15 years you will need to pay out $80,000 to clear the loan. Your monthly loan payment is calculated as:
|
| PPmt(rate, period, periods, presentMoney, futureMoney, type)
Overloads:
|
| A Number value. |
| |
| PV(rate, periods, payment, futureMoney, type)
Overloads:
| This function returns a number specifying the present value of an annuity based on periodic, fixed payments to be paid in the future and at a fixed interest rate. |
| A Number value. | Suppose that you want to buy a condo and can make payments of $1100 twice a month (24 annual payments). If the mortgage rates are 6.5 percent, and you want to pay off the condo in 10 years, what is the maximum loan that you can take out?
You can therefore afford a loan of about $194,000. Notice that the payment argument is negative since you are paying out the money each month. |
| Rate(periods, payment, presentMoney, futureMoney, type, guess)
Overloads:
| This function returns a number specifying the interest rate per period for an annuity. The units of the return value are consistent with the units of periods. For example, if periods is in months, the rate returned is a monthly interest rate. |
| A Number value. | An electronics store offers to finance a $12500 television for $560 per month, over 2 years, with no money down. Is this a good deal? The first step in determining this is to figure out what interest rate the store is charging.
The next expression calculates the interest rate, expressed as a yearly interest rate and as a percent.

When using the Math functions, if you assign a field to a variable, for example "x", the variable "x" loses the characteristic of representing a group of values. The following formulas are then incorrect.
Number x = @dbfield;
Number y = Average(x); // system will prompt you that there is no such kind of function.Number x = @dbfield;
Number y = PopulationStdDev(x); // system will prompt you that there is no such kind of function.
Rounding Mode
The parameter c in the function Round(Number a, integer b, integer c) is used to represent the following different seven rounding modes, which you can specify as an integer between 0 and 6.
- ROUND_UP = 0
Rounding mode to round away from zero. Always increments the digit prior to a non-zero discarded fraction. Note that this rounding mode never decreases the magnitude of the calculated value. - ROUND_DOWN = 1
Rounding mode to round towards zero. Never increments the digit prior to a discarded fraction (that is, truncates). Note that this rounding mode never increases the magnitude of the calculated value. - ROUND_CEILING = 2
Rounding mode to round towards positive infinity. If the value is positive, behaves as for ROUND_UP; if negative, behaves as for ROUND_DOWN. Note that this rounding mode never decreases the calculated value. - ROUND_FLOOR = 3
Rounding mode to round towards negative infinity. If the BigDecimal is positive, behave as for ROUND_DOWN; if negative, behave as for ROUND_UP. Note that this rounding mode never increases the calculated value. - ROUND_HALF_UP = 4
Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round up. Behaves as for ROUND_UP if the discarded fraction is >= .5; otherwise, behaves as for ROUND_DOWN. Note that this is the rounding mode that most of us were taught in grade school. - ROUND_HALF_DOWN = 5
Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round down. Behaves as for ROUND_UP if the discarded fraction is > .5; otherwise, behaves as for ROUND_DOWN. - ROUND_HALF_EVEN = 6
Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor. Behaves as for ROUND_HALF_UP if the digit to the left of the discarded fraction is odd; behaves as for ROUND_HALF_DOWN if it's even. Note that this is the rounding mode that minimizes cumulative error when applied repeatedly over a sequence of calculations.

Soundex(string)
You need to pay attention to the following when using this function:
- The value string must be in quotes.
- Soundex works only with values that begin with the same letter. For example, Soundex returns the same value for Chris and Cris C620 but not for Kris K620. Soundex creates a code based on the first character in the string plus three characters based on the following:
- Non-alpha characters like numbers and punctuation become -1.
- The characters "a", "e", "i", "o", "u", "y", "h", and "w" are ignored (except when they are the first character in the original string).
- The characters "b", "f", "p", and "v" become 1.
- The characters "c", "g", "j", "k", "q", "s", "x", and "z" become 2.
- The characters "d" and "t" become 3.
- The character "l" becomes 4.
- The characters "m" and "n" become 5.
- The character "r" becomes 6.
- If the resulting code is only two or three characters long, Soundex uses zeros to fill it out to four characters. For example, in the name Lauren, only "L", "r", and "n" are translated (Lrn), so the resulting Soundex code becomes L650.
- If the resulting code is more than four characters long, Soundex ignores all characters after the fourth character. For example, in the name Patrick, "P", "t", "r", "c", and "k" can be translated (Ptrck), but the resulting Soundex code is only four characters P362.
ToText(Time a, String b, String c, String d)
You need to pay attention to the following when using this function:
