Logi Report provides the following four types of formula operators: Math, Comparison, Boolean, and Others. This topic describes the usage of each operator with examples.

Math

OperatorDescriptionExample
date x + integer yWhen a Date value is added to an Integer value, the return value will be a Date value because the Integer value will have changed 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 a DateTime value is added to an Integer value, the return value will be a DateTime value because the Integer value will have changed 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 returning value's precision will correspond 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 will be a BigDecimal.

Note: 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 will be the data type with the higher precision. For example, if an Integer is added to a Double, the return value will be a Double value.

The return value of the following expression is 81.71.

55 + 26.71

For the real number type data, Currency has the highest precision while float has the lowest precision. So, if two numeric datum of different precision are sub traced from each other, the return value will be of the data type with the higher precision.
