You can add 0.5 for rounding, or use Math.round instead of casting. – Peter Lawrey Jul 29 '13 at 16:19

check the length of the number. If the length is less than five or eight, concatenate the necessary amount of zeros. If the length is greater than five or eight, use the substring method. Hope this helps
