Subject: math/pow10: remove overlapping boundary (n=0)
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=c04335e33a6915ae4edc9c9f94a909a46557f99a;p=gostls13.git

math/pow10: remove overlapping boundary (n=0)

Both the first and second conditions include n=0, creating an
implicit logic that relies on order of evaluation.
