UKismetMathLibrary::Less_DoubleDouble
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns true if A is strictly less than B (A < B). This is the Blueprint 'float < float' comparison node.
Caveats & Gotchas
- • Strict inequality — returns false when A == B. For threshold checks where equality should pass, use LessEqual_DoubleDouble instead.
- • Do not use this to compare values that were produced by floating-point arithmetic and are expected to be equal — use NearlyEqual_FloatFloat for equality testing to avoid false negatives from rounding.
