what would be the easiest way to strip the whole number of the double....ie.

37.39283

to the value of 39283

I just need to get the fraction out of it, I thought it would be simple at first by
double x = 37.39283;
double y;

y = (x % 1);

but doh......only can use that for integers.  Any other simple suggestions?

well damn I am dumb.......this is what I just did, but hell.....its been to long since I have done this :(.

     memset(buffer, 0, 64);
     sprintf(buffer, "%f", x);

     if(!buffer)
     {
          return;
     }

     decimalPlace = strstr(buffer, ".");          // search for the decimal point

     decimalPlace++;                                   // advance past decimal point
     y = (double)strtol(decimalPlace, 0,10);

I think I will be using your's thanks
