UKismetStringLibrary::BuildString_Double
#include "Kismet/KismetStringLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Builds a new string in the form AppendTo+Prefix+InDouble+Suffix by formatting a double value and concatenating it between the given prefix and suffix.
Caveats & Gotchas
- • Despite the Blueprint display name 'Build String (Float)' and the parameter being a double, the underlying implementation still uses FString::SanitizeFloat, so the printed precision matches SanitizeFloat's rounding rather than the full double precision.
- • AppendTo is not modified in place — the function preallocates and returns a brand-new FString on every call, so chaining many BuildString_ nodes to construct one long string is less efficient than accumulating with FString::Append.
