double DoubleVal{ 9.2f };
	
// Using FString::Printf	
FString ValuePrintf{ FString::Printf(TEXT("The value is: %lf."), DoubleVal) };
UE_LOG(LogTemp, Warning, TEXT("Printf version: [%s]"), *ValuePrintf);
//>> Printf version: [The value is 9.200000.]

// Using FString::SanitizeFloat;
FString ValueSanitizeF{FString::SanitizeFloat(DoubleVal, 2)};
UE_LOG(LogTemp, Warning, TEXT("SanitizeFloat version: [%s]"), *ValueSanitizeF);
//>> SanitizeFloat version: [9.20]
//Note: The first parameter in SanitizeFloat is actually a double.
//Note: SanitizeFloat strips trailing zeros; use the second parameter to force 
//a certain amount of fractional digits (zero-padded if actual digits are not 
//present; e.g., given 1.1 with the second argument of 3 would yield "1.100")
