Member of: Math Script
Calculates the largest integer less than or equal to the passed in value.
Syntax
int Function Floor(float afValue) native globalParameters
- afValue: The value to get the floor of.
Return Value
The floor of the passed-in value.
Examples
int x = Math.Floor(2.1) ; x == 2
int y = Math.Floor(5.9) ; y == 5
int z = Math.Floor(-0.7) ; z == -1Notes
- Casting a Float to an Int verifiably produces the same results for positive numbers and is measurably faster. Results with negative numbers differs since casting truncates the number going towards 0 while floor gets the closest lower integer, therefore going towards negative infinite.
