```{index} single: gmp_lib_version; Math::GMP function ``` ```{index} single: Math::GMP::gmp_lib_version; Perl function ``` # gmp_lib_version Return the version of `libgmp` currently loaded into the process. ## Synopsis ```perl my $v = Math::GMP::_gmp_lib_version(); print "running libgmp $v\n"; # e.g. "running libgmp 6.3.0" ``` ## What you get back A dotted-decimal string like `"6.3.0"`. Feed it to `version->parse` if you need numeric comparison. ## Differences from upstream Upstream returns a vstring. This implementation returns a plain string; both compare the same way under `version->parse` and under string `ge` / `le`.
