UKismetMathLibrary::Divide_Int64Int64

Description
Divides two 64-bit integers using integer (truncating) division (A / B). Division by zero is reported via ReportError_Divide_Int64Int64 and returns 0.
Caveats & Gotchas
- • Division is truncated toward zero, not floored. -7 / 2 returns -3, not -4. If you need floor division for negative numbers, handle the sign manually.
- • Dividing by zero does not crash — UE calls ReportError_Divide_Int64Int64 which logs an error and returns 0. However, silently returning 0 can cascade into incorrect game logic. Validate B != 0 before calling in production code.
