From d179018e4c9561afac5ca5c8878852f1171b836b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pali=20Roh=C3=A1r?= Date: Mon, 12 Sep 2022 21:02:27 +0200 Subject: [PATCH] display_options: print_size: Fix order overflow MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Function print_size() round size to the nearst value with one decimal fraction number. But in special cases also unit order may overflow. For example value 1073689396 is printed as "1024 MiB" and value 1073741824 as "1 GiB". Fix this issue by detecting order overflow and increasing unit order. With this change also value 1073689396 is printed as "1 GiB".
