UKismetMathLibrary::Add_DoubleDouble
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns the sum of two doubles (A + B). This is the Blueprint 'float + float' addition node, renamed to use double in UE5.
Caveats & Gotchas
- • In UE5 Blueprint, the 'float' type is actually double precision — this function's 'DoubleDouble' suffix reflects the underlying storage, not a separate type visible to Blueprint users.
- • In C++ code, prefer the built-in '+' operator directly; this wrapper has no benefit outside of Blueprint exposure.
