If users accidentally enter a big number e.g. in Home > Patrons > Manual
invoice, Koha fails with an Internal Server Error in Price.pm

To reproduce, enter a value of: 99999999999999

Plack error log says:
Template process failed: undef error - round() overflow. Try smaller precision
or use Math::BigFloat at /home/marc/koha/Koha/Number/Price.pm line 44.

After that error, the detail page of the user where the invoice was applied can
no longer be displayed, it produces the same Internal Server Error

This is due to the fact that the big number is stored in table accountlines.

Setting to major because normal users can not recover from this situation.

To recover, you have to delete or update the records in table accountlines.

The same error can be produced with a manual credit.

The same error can occur in Administration > Patron Categories if the numbers
in the database are too big, see
http://irc.koha-community.org/koha/2017-06-09#i_1942793
...but it can not be reproduced by entering a big number. Biggest number you
can enter is: 99999999
