How do I display "5" as "05" or "005"?

Thanks.

In what language?

Edit: pardon my ignorance I didn't pay attention to which category this was posted in. ;-)
Anyway I'm not familiar with MetaTrader's MQL 4, but you should probably look for a padding function that converts the integer into a string and prepends the required number of zero's to match the required string length.

MetaTrader's, of course.

Thanks, RubenE.

GJ, MetaTrader, of course.

I checked out the MQL docs a bit and came up with this:

string Pad(int number, int requiredLength)
{
string strNumber = number;
string strNewNumber = "";
int intDiff = StringLen(strNumber) - requiredLength;
if (intDiff > 0)
{
for (intCurChar = 0; intCurChar < intDiff; intCurChar++)
{
strNewNumber += "0";
}
strNewNumber += strNumber;
}

return strNewNumber;
}

Please note that I didn't test this and this is the first piece of MQL I ever wrote, but it should give you an idea of how to do this. Is this what you had in mind?

Yes, thanks, it's pretty much the sort of thing. I will have to investigate the precise details. Shame it can't be set to display numbers formatted such that 3 digits are always showing.

 

[RubenE]

Yeah most languages have builtin formatting functions for integers, but I couldn't find them in the MQL reference. Then again, maybe there is and I just didn't see it. Someone with some MQL experience might be able to tell you.

[shadowninja]

Yeah, likewise, looked all over the place but nothing.

 

[RubenE]

In that case a custom function like the example I made should do the trick. Again not tested, so it might bother your cat or even drink all the beer from your fridge. Use at your own risk. ;-)
