UKismetMathLibrary::NotEqualExactly_Vector4Vector4
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns true if any component of A differs bitwise from the corresponding component of B. Logical inverse of EqualExactly_Vector4Vector4.
Caveats & Gotchas
- • Like EqualExactly, this uses exact floating-point comparison. It is not appropriate for detecting 'meaningfully different' vectors that arise from computation — use NotEqual_Vector4Vector4 with a tolerance for that.
- • Two vectors where one component contains NaN will always return true here, because NaN != NaN under IEEE 754.
