arf_randtest, arf_randtest_not_zero, arf_randtest_special
Synopsis
#include <flint/arf.h>void arf_randtest(arf_t x, flint_rand_t state, slong bits, slong mag_bits)sourcevoid arf_randtest_not_zero(arf_t x, flint_rand_t state, slong bits, slong mag_bits)sourcevoid arf_randtest_special(arf_t x, flint_rand_t state, slong bits, slong mag_bits)sourceSet x to a random finite number with a mantissa of at most bits bits and an exponent of at most mag_bits bits, with a non-uniform distribution that favours corner cases. The second version never returns zero; the third sometimes returns \pm\infty or NaN.
