Subject: When displaying sizes as a floating-point number (e.g. "123.4 Mb"),
X-Git-Url: https://git.distorted.org.uk/~mdw/sgt/agedu/commitdiff_plain/815e510ac8f79ac0c3ba2032a98e919e43df1a02

When displaying sizes as a floating-point number (e.g. "123.4 Mb"),
don't compute that number in integer arithmetic and then cast it to
double!
