Expand a random range from 1–5 to 1–7
...re is no (exactly correct) solution which will run in a constant amount of time, since 1/7 is an infinite decimal in base 5. One simple solution would be to use rejection sampling, e.g.:

i = 5 * (rand5() - 1) + rand5(); // i is now uniformly random between 1 and 25
} while(i > 2...
