- * 0 doesn't have an exponent, therefore the returned exponent in this case
- * isn't really important. We choose to return __gmpfr_emin because
- *   1) it is in the exponent range [__gmpfr_emin,__gmpfr_emax],
- *   2) the smaller a number is (in absolute value), the smaller its
- *      exponent is. In other words, the f -> exp function is monotonous
- *      on nonnegative numbers.
- * Note that this is different from the C function frexp().
