Convert hex to Decimal and keep leading zeros..

Hi,

I hope you can help?

How to convert hex to Decimal and keep leading zeros

I read 002C, hex, and I want to convert it to 0044 decimal.

sscanf (MyNum, "%4x", &DecNum); will only give me 44.

It have been working up till I started to get leading zeros.

We will always have a 4 digit hex input in a range

We must have the leading 00 in this case.

How is this best done?

Thanks for the help

Hi,

I don't really understand your problem. Is this stuff what you need ?

int main (int argc, char *argv[])
{
	const char MyNum[] = "002C";
	int DecNum;
	
	sscanf (MyNum, "%4x", &DecNum);
	printf ("%04d", DecNum);
	getchar ();

	return 0;
}

"0044" appears on standard output when printf function executes...
