Subject: [PATCH] Print heuristics probability fraction part with 2 digits.
Date: Thu, 26 Jul 2018 14:43:00 -0000 [thread overview]
Message-ID: <c179c1ca-4a1e-5df2-f730-774b243e8f7d@suse.cz> (raw)

Hi.
It's just a cosmetics change where I want to print 2 digits of fraction
part of heuristics probabilities. It helps to distinguish 100% from
PROB_VERY_LIKELY (99.96%).
Patch can bootstrap on ppc64le-redhat-linux and survives regression tests.
Ready to be installed?
Martin
