Specifiers: staticUFUNCTIONBlueprintPure
Description
Subtracts B from A and returns the result as an int64. Exposes the integer64 subtraction operator to Blueprint graphs.
Caveats & Gotchas
- • No overflow protection — if A - B underflows past INT64_MIN (-9,223,372,036,854,775,808) the result wraps around silently in C++. Blueprint does not surface this as an error.
- • B defaults to 1, matching the decrement idiom used by the Blueprint compact node. Be explicit when calling from C++ to avoid ambiguity with the default.

Subtract two int64 values C++
int64 A = 10000000000LL;
int64 B = 3000000000LL;
int64 Result = UKismetMathLibrary::Subtract_Int64Int64(A, B); // 7000000000Tags
