Description

This is probably just a rounding bug, but it is still a little bit frustrating when you notice it.
As you can see from the screenshot, the percentages are
COBOL 45.7%
Assembly 43.2%
Shell 5.9%
Ruby 5.3%
which is 100.1% in total.

I've made a copy of my repo here:

This is more than likely due to rounding to 1decimal place.
changing it to 2dp would slightly improve it but I doubt this will truly ever be solved due to how floats work and all you need is the perfect combination of odd-count languages detected and odd-count files counted for it to manifest itself at some decimal position

There are different things you can do to avoid such problems, like the largest remainder method.
I might try implementing it to where ever it generates the stats later, I've just never used go before.

Then please have a look at models/repo/language_stats.go#44-67.
