* In various functions, use mpfr_equal_p() instead of mpfr_cmp() == 0.vlefevre2021-04-231-2/+2
| | | | | | | | | Note: In these cases, the test should be false if one of the arguments is NaN (it is not always clear whether NaN is impossible, but just in case, mpfr_equal_p is safer, in particular if the code around changes; and this is more readable too). git-svn-id: https://scm.gforge.inria.fr/anonscm/svn/mpfr/trunk@14493 280ebfd0-de03-0410-8827-d642c229c3f4
