Subject: scripts/bloat-o-meter: fix percent on <1% changes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8cde0daf6c4cca8babec4861a1ce7f8875edf879;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

scripts/bloat-o-meter: fix percent on <1% changes

Python divisions are integer divisions unless at least one parameter is
a float.  The current bloat-o-meter fails to print sub-percentage
changes:

  Total: Before=10515408, After=10604060, chg 0.000000%

Force float division by using one float and pretty the print to two
significant decimals:

  Total: Before=10515408, After=10604060, chg +0.84%
