UKismetMathLibrary::Abs_Int64
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns the absolute (non-negative) value of A. Returns A unchanged if A >= 0, or negates A if A < 0.
Caveats & Gotchas
- • Abs_Int64(INT64_MIN) is undefined behaviour in C++ — INT64_MIN has no positive counterpart in a signed 64-bit integer (two's complement). Defensively clamp or check for INT64_MIN before calling if the input can reach that value.
- • For distances or magnitudes where you also need the sign separately, call SignOfInteger64 before Abs_Int64 rather than after — once negated, the sign information is discarded.

int64 Example
Compute the magnitude of a signed offset C++
int64 Offset = GetSignedOffset(); // may be negative
int64 Distance = UKismetMathLibrary::Abs_Int64(Offset);
if (Distance > Threshold)
{
ApplyCorrection(Offset);
