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

// Using FString::SanitizeFloat; 
FString ValueSanitizeF{ FString::SanitizeFloat(FloatVal, 2) };
UE_LOG(LogTemp, Warning, TEXT("SanitizeFloat version: [%s]"), *ValueSanitizeF);
//>> SanitizeFloat version: [9.20]
//Note: this also works for doubles, as 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")
