Making numbers with pow()

[mrchaos]

I have a 4 positon array with characters (numbers) stored in it. For example 49, 50, 51, 52...which would be 1,2,3,4 respectively. What I want to do is build the number 1234 out of the array. This is the code I have so far and it doesn't seem to wanna work.

j=iFieldSz;
     for(i=0;i<iFieldSz;i++) {
          itemp = (int)(number[i] - 48);
          inumber += itemp * pow(10.0,(double)j);
          j--;
     }
     printf("%d",inumber); 

any help would be great
