UKismetMathLibrary::LessEqual_DoubleDouble
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns true if A is less than or equal to B (A <= B). This is the Blueprint 'float <= float' comparison node.
Caveats & Gotchas
- • Uses exact equality for the equal case — computed floats that are theoretically equal may fail due to floating-point rounding. For computed boundaries, add a small epsilon or use NearlyEqual_FloatFloat + Less_DoubleDouble.
- • Semantically equivalent to !Greater_DoubleDouble(A, B), but prefer this form for readability in Blueprint graphs.
