Zdenek Kabelac 7c9fd3ea84 Don't use floor() in _bitset_with_random_bits ... Use _even_rand() function instead of floor() in _bitset_with_random_bits(). floor() function is missing in dietlibc (on architectures other than x86). Moreover using floor() to clip rand results does not assure even result distribution. _even_rand() uses integer arithmetic only and is designed to return evenly distributed results. > Looks OK to me. It took a while to decipher what is the exact meaning of > the loop in _even_rand (to a non-pseudorandomness-expert) but I am > fairly comfortable with it now. If I understand this correctly, it > rejects numbers that come from an "incomplete" slice of the RAND_MAX > space (considering the number space [0, RAND_MAX] is divided into some > "max"-sized slices and at most a single smaller slice, between [n*max, > RAND_MAX] for suitable n -- numbers from this last slice are discarded > because they could distort the distribution in favour of smaller > numbers).
