WebApr 16, 2024 · Mathematically speaking, using a cryptographically secure random number generator should yield a truly random set. The problem is clamping: if we simply take val % 10 to reduce it to our desired \$[0, 9]\$ range, we'll find that we have a slight favoritism / bias towards numbers at the lower end of the set. In fact, we should have the most bias ...
