+Fixed a bug in the L<perlapi/sv_numeq> API where values with numeric
+("0+") overloading but not equality or numeric comparison overloading
+would always be compared as floating point values.  This could lead to
+large integers being reported as equal when they weren't.

+Added L<perlapi/sv_numne>, sv_numle, sv_numlt, sv_numge, sv_numgt and
+L<perlapi/sv_numcmp> APIs that perform numeric comparison in the same
+way perl does, including overloading.  Separate APIs for each
+comparison are needed to invoke their corresponding overload when
+needed.  Inspired by [GH #23918]
