Member of: Math Script
Calculates the largest integer less than or equal to the passed in value.
Syntax[edit | edit source]
int Function Floor(float afValue) native global
Parameters[edit | edit source]
- afValue: The value to get the floor of.
Return Value[edit | edit source]
The floor of the passed-in value.
Examples[edit | edit source]
int x = Math.Floor(2.1) ; x == 2
int y = Math.Floor(5.9) ; y == 5
int z = Math.Floor(-0.7) ; z == -1
Notes[edit | edit source]
- 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.
int floored = Math.Floor(-0.7) ; result is -1
int casted = -0.7 as int ; result is 0
