IntegerToStr Function???

Okay, there's a DoubleToStr() function, a StrToDouble() function and a StrToInteger() function ... but, is there an IntegerToString()??? Apparently there isn't, at least according to the MetraTrader reference.

What I'm trying to do is convert an array of integer variables into an array of string variables. However, without the ability to convert it directly, this is what I have to do:

PHP Code
   dig[1]="01"; dig[2]="02"; dig[3]="03"; dig[4]="04"; dig[5]="05"; dig[6]="06";
   dig[7]="07"; dig[8]="08"; dig[9]="09"; dig[10]="10"; dig[11]="11"; dig[12]="12";
   dig[13]="13"; dig[14]="14"; dig[15]="15"; dig[16]="16"; dig[17]="17"; dig[18]="18";
   dig[19]="19"; dig[20]="20"; dig[21]="21"; dig[22]="22"; dig[23]="23"; dig[24]="24";
   for(int i=1; i<=24; i++)
     {
      string mag[i]="magic #"+dig[i];
     }
Now, if there were such a conversion function available, this I believe is all I need to do below:

PHP Code
 for(int i=1; i<=24; i++)
     {
      string dig[i]=IntegerToStr(i);
      string mag[i]="magic #"+dig[i];
     }
Any ideas?

Thanks!

DoubleToStr([Integer Value], 0);


If you set the digits to 0, there will be no decimal, thus, an integer.

Ron had a good idea. Sometimes you might want the result to have a leading "0" tho,so:
if iSomeInteger > 9
string sX = "" + iSomeInteger
else
string sX = "0" + iSomeInteger //this is an implied type cast change

or
string sX = "00000" + iSomeInteger
then get it's length,
then clip off the right most 2 digits (if you are bored!)

Okay guys, this is what I came up with:

PHP Code
string mag[25],dig[25],zero;

//+------------------------------------------------------------------+
//| expert initialization function                                   |
//+------------------------------------------------------------------+
int init()
  {
//----
   for(int i=1; i<=24; i++)
     {
      dig[i]=DoubleToStr(i,0); zero=""; if(i<10){ zero="0"; }
      mag[i]="magic #"+zero+dig[i];
     }
//----
   return(0);
  }
Ron, I don't think you intended for me put the integer value within the brackets, because it doesn't work that way.

Ken, you are correct about adding the additional "0" which, is how I intended it to display it initially. Basically I had it set up as shown, but it wouldn't work without converting the integer.

So, how does the code look? It appears to be working and shows up correctly in the comments field when back testing. Should know for certain on Sunday when I can forward test it.


Thanks guys!

If you want a more sophisticated function for converting numbers (integer or double) to strings, including floating signs, comma insertion, rounding, currency symbols, zero suppression, etc, you might like to check out this post. There's a date/time formatting function there also.

What, there's more? It sounds a little bit too advanced for what I'm working on. I think the code shown (so long as it's correct) should suffice. But, I will have a look at it.

Thanks!
