I'm trying to detect if an entry in a uitextfield is a number or not but isnan does not seem to work.

	NSString * bLong = [NSString stringWithFormat:@"%@",maLong.text];
	NSString * bLat = [NSString stringWithFormat:@"%@",maLat.text];

	if(isnan([bLat floatValue]) || isnan([bLong floatValue])){
		return;
	}

What am I doing wrong here?
