UKismetMathLibrary::Multiply_ByteByte
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Multiplies two byte (uint8) values and returns the result as a byte. In Blueprints this is the 'Byte * Byte' node, used for compact 8-bit arithmetic such as flags, indices, or shader parameter packing.
Caveats & Gotchas
- • The result is silently truncated to uint8 (0–255) — if A * B exceeds 255 the high bits are discarded without any overflow indication. For example, 200 * 2 = 144, not 400. Check your value ranges before using byte multiplication for gameplay logic.
- • Blueprint's byte type maps to uint8; it cannot represent negative values. Use integer arithmetic if you need signed intermediate results.
Signature

| Name | Type | Description | Default |
|---|---|---|---|
| A | uint8 | First byte operand (0–255). | — |
| B | uint8 | Second byte operand (0–255). | — |
Return Type
uint8 Example
Scale a byte property by a small multiplier C++
uint8 BaseSpeed = 10;
uint8 Multiplier = 3;
uint8 FinalSpeed = UKismetMathLibrary::Multiply_ByteByte(BaseSpeed, Multiplier); // 30See Also
