How to format convert int32 to FString?

Like the title, say if I have a number “3”, the convert result should be “003”, if I have a number “33”, the convert result should be “033”, so on and so forth.
Right now I have a simple implementation like below

FText UFPWeaponInfo::IntToFText(int32 Num)
{
	// TODO: Optimize the logic so it doesn't look as stupid as now.
	if (Num >= 100)
	{
		return FText::FromString(FString::FromInt(Num));
	}
	else if (Num >= 10)
	{
		return FText::FromString(FString("0") + FString::FromInt(Num));
	}
	else
	{
		return FText::FromString(FString("00") + FString::FromInt(Num));
	}
}

This works but it’s just too “stupid”, is there any better way to do this like a Format or something?

Hi there!
you can use FString::Printf to format the integer with leading zeros.
I created function and this should solve your problem

FText UFPWeaponInfo::IntToFText(int32 Num)
{
FString FormattedNum = FString::Printf(TEXT("%03d"), Num);
return FText::FromString(FormattedNum);
}

if I made any mistake in understanding your problem, please let me know

Cool, this is exactly what I’m looking for, thank you!

The proper way of doing it is using the FString member FString::FromInt(int). e.g.:

__int32 myInt = 30;
FString myString = FString::FromInt(myInt); // myString would get the value "30"
