UKismetMathLibrary::FFloor
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPureUFUNCTION
Description
Rounds A down towards negative infinity, returning the largest integer less than or equal to A. -1.6 becomes -2 and 1.6 becomes 1.
Caveats & Gotchas
- • Returns int32, so values outside [-2147483648, 2147483647] will overflow silently. Use FFloor64 for large values.
- • Blueprint displays this node as 'Floor' — the C++ name FFloor reflects the legacy float naming convention but the function now accepts double.
