Variables

dig d_int64 dig;: number of decimal digits of precision
epsilon real_t epsilon;: smallest increment to the value 1
infinity real_t infinity;: infinity value
mant_dig d_int64 mant_dig;: number of bits in mantissa
max real_t max;: largest representable value that's not infinity
max_10_exp d_int64 max_10_exp;: maximum int value such that 10^{max_10_exp is representable}
max_exp d_int64 max_exp;: maximum int value such that 2^max_exp-1 is representable
