UKismetMathLibrary::Conv_ByteToInt64
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPureBlueprintAutocast
Description
Widens a byte (uint8) to a 64-bit integer. Lossless; result is always in the range 0–255.
Caveats & Gotchas
- • Lossless widening — all 256 possible byte values are exactly representable as int64. No clamping or special handling is needed.
- • Introduced alongside the int64 Blueprint type in UE5. If you need this in UE4, widen to int32 first with Conv_ByteToInt and then rely on implicit narrowing — or handle the widening manually.
