Subject: Use the correct algorithm to find the bound.
X-Git-Tag: v0.1~111
X-Git-Url: https://bilbo.iut-bm.univ-fcomte.fr/and/gitweb/loba.git/commitdiff_plain/8996be78fd84b1a3e10a2b7e66b264e28b524ebd?ds=sidebyside

Use the correct algorithm to find the bound.

Should not change result, just be slightly faster.
