Subject: [PATCH] Fix formatting of some larger file sizes on 32bit x86
|
|
|
|
With the x87 FPU available, GCC uses long double precision for some variables.
|
|
Due to the function call passing a double, some comparisons break down.
|
|
That resulted in "1.00 YB" being printed as "1000.00 ZB" instead.
|
|
|
|
Fixes #85
