UKismetMathLibrary::Percent_Int64Int64
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Returns the remainder of 64-bit integer division (A % B). The result has the same sign as A (C++ truncating remainder semantics).
Caveats & Gotchas
- • The result sign follows A, not the mathematical modulo convention. For A = -7, B = 3: result is -1, not 2. If you need a non-negative modulo for circular indexing, add B and take % again: ((A % B) + B) % B.
- • Like Divide_Int64Int64, dividing by zero calls ReportError_Percent_Int64Int64 and returns 0 silently. Guard against B == 0.
