UKismetMathLibrary::MultiplyMultiply_FloatFloat
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns Base raised to the power of Exp (Base^Exp). Wraps std::pow and is exposed to Blueprint as the ** (Power) node.
Caveats & Gotchas
- • A negative Base with a non-integer Exp returns NaN because the mathematical result is complex. Check that Base >= 0 when the exponent can be fractional, or take the absolute value of Base and track sign separately.
- • This function takes and returns double, but in UE4 Blueprint float pins were 32-bit — code compiled against an older engine targeting UE4 float precision may see unexpected precision differences compared to UE5.

double Example
Scale damage exponentially with a combo multiplier C++
double BaseDamage = 50.0;
double ComboMultiplier = 1.2;
int32 ComboCount = GetComboCount();
double Damage = BaseDamage * UKismetMathLibrary::MultiplyMultiply_FloatFloat(ComboMultiplier, (double)ComboCount);Tags
