This bug report pertains to BigRat version 0.260802 running under perl 5.24.1: The man page SYNOPSIS gives this usage example for creating a BigRat infinity: my $y = Math::BigRat->new('inf'); On my setup, the above fails with: "Use of uninitialized value $x in concatenation (.) or string at /xxxx/xxxx/locperl/lib/perl5/Math/BigInt/Calc.pm line 1240." Example inline below. Show quoted text

---------- begin inline example -------------------- #!/usr/bin/perl use strict; use warnings; use Math::BigRat; print "BigRat version $Math::BigRat::VERSION\n"; my $y = Math::BigRat->new('inf'); ----------------------------------------------------

Glenn, thank you for your report. Could you supply more information about your setup, namely the output of these commands: perl -V perl -MMath::BigInt -le "print Math::BigInt->VERSION" Note that there are incompatible combinations of versions of Math::BigInt and Math::BigRat. You might have hit one of these by updating Math::BigInt from CPAN while keeping Math::BigRat from your perl core distribution. Note also that there is an important patch for Math::BigRat versions from 0.260805 through 0.2612 (the latest published one) in rt-121139, cf. https://rt.cpan.org/Ticket/Display.html?id=121139 -Martin On Mon Jun 05 22:57:17 2017, gdg@zplane.com wrote: Show quoted text

That's exactly what the problem was, thank you. I had forgotten that I'd even had BigInt installed in my local library. My mistake for not running it with the debugger to see where it was coming from. I udpated both my local BigRat and BigInt, and now the 'inf' init is fine. Sorry for the noise.
