Math Operators

OperatorDescriptionExample
date x + integer yWhen you add a Date value to an Integer value, the return value is a Date value because the Integer value can change to a Date value.If the date is Oct. 15, 1999, the return value of the following statement is "10-25-99".

ToDate (1999, 10, 15) + 10

datetime x + integer yWhen you add a DateTime value to an Integer value, the return value is a DateTime value because the Integer value can change to a DateTime value.If the datetime is Aug. 10, 1999 10:21:30, the return value of the following statement is "1999-08-10 10:21:40".

ToDateTime (1999, 8, 10, 10, 21, 30) + 10

numeric x + yAdds x and y, and numeric adds to numeric. The return value's precision corresponds to the data type with the higher precision except when a BigInt value is added to a real number. In this case, the return value is a BigDecimal.

Note icon Each data type has its own precision. For the Integer type data, BigInt has the highest precision while integer has the lowest precision. For the real number type data, Currency has the highest precision while Float has the lowest precision. So, if two numeric data fields of different precision are added together, the return value is the data type with the higher precision. For example, if an Integer is added to a Double, the return value is a Double value.

The return value of the following expression is "81.71".

55 + 26.71

string x + boolean yWhen you add a String to a Boolean value, the return value is a String because the Boolean value can change to a String value, while the String value cannot change to a Boolean value.The return value of the following statement is "It is false".

Note icon Each data type has its own precision. For the Integer type data, BigInt has the highest precision while integer has the lowest precision; for the real number type data, Currency has the highest precision while float has the lowest precision. Therefore, if two numeric datum of different precision are substraced from each other, the return value is of the data type with the higher precision. For example, if an Integer is subtracted from a Double, the return value is a Double value.

Boolean Operators

The following are a set of truth tables showing the logic operations for 3-valued logic.

A AND BTrueFalseNull
True True False Null
False False False False
Null Null False Null

A OR B True False Null
True True True True
False True False Null
Null True Null Null

A NOT A
True False
False True
Null Null

The following table shows the usage about the Boolean operators：

OperatorDescriptionExample
Boolean x || Boolean yReturns "true" if x is true or y is true.

Integer s=4,d=8;
Integer f=6;
if ( f>s || f>d )
{
return "abc";
} - Returns "abc".

if ((@"Annual Sales" > 50000) ||(@"Annual Sales"<0)) then
"Customer needs attention"
else
"Normal customer"

If( ! isNull(@customerId) && ! isNull(@country)){
               If(@customerId > 10 || @country == ‘USA’){
                              Integer newId =  @customerId + 1;
}
}
Else{
               // Some error processing logic here
}

Boolean x && Boolean yReturns "true" if x is true and y is true.

Integer s=4,d=8;
Integer f=6;
if ( f>s && f<d )
{
return "abc";
} - Returns "abc".

if ((@"Annual Sales" <3000) && (@Customers_Country=="USA")) then
"Customer is in the USA and Annual Sales is less than 3000"
else
"Others"

! Boolean xReturns "true" if x is false.The return value of the following statement is "def".

Integer s=4, d=8;
Integer f=6;
if ( ! ( f>s ) )
return  "abc"
else
