Function: Floor
Description
Rounds a number down to the previous multiple of number2, if specified.
Syntax
Floor(number[,number2])
Arguments
Number is the value to be rounded. The number can be a constant, a numeric field, an expression that results in a number, or a function that returns a number.
Number2 is the optional multiple to which number is to be rounded. If this is not specified then it defaults to 1.0 (or -1.0) causing rounding/truncating to the nearest integer.
Return value
This function returns a number. If number2 is zero, or if the sign of number2 differs from the sign of number, then this function returns a null value.
Calculated field examples
If the Unit_price field contained the value 2.5, the following calculated field expression would return the number 2: Floor(Unit_price,1)
If the Unit_price field contained the value 12.46, the following calculated field expression would return the number 12.25: Floor(Unit_price,0.25)
Filter/Find example
Records with a Unit_price field value of 35.49 or 35.17 can be selected or found using the expression: Floor(Unit_price,0.50)=35
