This rule is often ignored by non accountants, as the previous discussion.
(0.101 was the right answer)

Reports must be "acurate", which means cents must be exact.
In many audits, only cents are checked first because it is fast. If cents
are not correct, then it's usually not needed to control any further. The
report is rejected.
There is no problem in daily accounting because all devices calculate in BCD
for this reason. The first hand-held calculator since 70s, and any
spreadsheet with the "finance" format does it. A cashier has to calculate in
BCD.
Accountants have never learnt one can calculate differently than in base
ten, so you'll probably not find a law. Anyway, regarding French legals,
there are more important reasons to be careful.
