How to use sass --precision?

Question

I am trying to use sass + compass to make a fluid grid and I need my %'s to have at least 8 digits when compute them out but right now sass + compass is rounding my decimals to 3-digits. I found that if use --precision you can tell sass to round to how ever many digits you want, my issue is that i can seem to figure out how to get --precision to work from the terminal on my project. Please help

Answer 1

According to this answer, configuring @precision in SASS's numbers.rb will achieve this result. It appears that --precision is nonfunctional.

Answer 2

sass --precision 6 input.scss output.css
