UKismetMathLibrary::Multiply_IntInt

Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Multiplies two integers and returns the product. Maps directly to the `int * int` Blueprint node.
Caveats & Gotchas
- • No overflow detection: multiplying large values (e.g. 100000 * 100000) silently overflows int32 and returns a garbage result. Use int64 arithmetic or clamp inputs when the product may exceed ~2.1 billion.
- • The result is a plain C++ int32 multiplication — no saturation, no checked-multiply. Unlike some game math helpers, there is no debug-mode assertion on overflow.
