Variables

dig long 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 long mant_dig;: number of bits in mantissa
max real_t max;: largest representable value that's not infinity
max_10_exp long max_10_exp;: maximum int value such that 10^{max_10_exp is representable}
max_exp long max_exp;: maximum int value such that 2^max_exp-1 is representable
min_10_exp long min_10_exp;: minimum int value such that 10^min_10_exp is representable as a normalized value
min_exp long min_exp;: minimum int value such that 2^min_exp-1 is representable as a normalized value
min_normal real_t min_normal;: smallest representable normalized value that's not 0
nan real_t nan;: NaN value
