I've been checking CPAN Tester results for one of my modules and noticed a single failure amidst a sea of passes. On checking it, is from Test::More is returning 0.99999999999999996 instead of 1.

My best guess is that the machine doing the testing has a peculiar build somewhere that is affecting the floating point arithmetic.

• Is that a fair assumption?
• Is there anything I can do about that?
• Is it worth doing anything about this?
