From 832b5776c7154e4506c38895e47d6c5b745a86f0 Mon Sep 17 00:00:00 2001 From: Nick Clemens Date: Tue, 18 Aug 2020 16:41:09 +0000 Subject: [PATCH] Bug 26239: Do not format large negative numbers At several places we got the following error if we use numbers too big for Number::Format Template process failed: undef error - round() overflow. Try smaller precision or use Math::BigFloat at /home/koha/src/Koha/Number/Price.pm line 44 It make the app explodes. The goal here is to handle these errors gracefully and easily. We fixed it for positive numbers in bug 15770, but we neglected the case of negative numbers Test plan: - Add a manual credit to a patron of 100000000000000 - ISE! - Apply patch - Restart all the things Works perfectly.
