math/p5-Math-BigInt: update to 1.999837 (from 1.999827)
 * Improve compatibility with older versions of the Math-BigRat distribution.
 * Re-enable upgrading in Math::BigFloat->bdiv().
 * Improvements to upgrading, downgrading, and rounding:
   . Fix bug related to upgrading in Math::BigInt->brsft() in Perl <= 5.16.
   . Fix Math::BigFloat->bpi().
   .  Improve as_int(), as_float(), and as_rat().
 * Improve methods div_scale() and round_mode() so they work better with
   subclasses. This fixes CPAN RT #125430.
 * Make div_scale() accept a Math::Big(Int|Float|Rat) object as input. This
   fixes CPAN RT #140599.
 * Add new methods numerator(), denominator(), and fparts().
 * Fix bug in to_ieee754(). Avoid that the significand overflows.
