Subject: [script] Use floor when implementing Int
X-Git-Tag: 0.8.0~76
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=437be1c6db2fb565adbcb0aad1ad7c35cdf9295d;p=thirdparty%2Fplymouth.git

[script] Use floor when implementing Int

Previously the Math.Int function converted to int and back to double.
The floor function works larger than those represented by integers and it
correctly handles NaN and Inf.
