UKismetStringLibrary::Conv_StringToDouble

function Engine Blueprint Since unknown

#include "Kismet/KismetStringLibrary.h"

Access: public Specifiers: staticBlueprintPureBlueprintAutocast

Description

Parses a string and returns the floating-point value it represents. This is the Blueprint 'String to Float' conversion node, which internally works in double precision.

Caveats & Gotchas

• Returns 0.0 for strings that can't be parsed, with no separate success flag to detect invalid input.
• Accepts leading whitespace and trailing non-numeric characters after the numeric portion (e.g. "3.14m" parses as 3.14) rather than rejecting the whole string.
