Ok, I have found it in global.scss
// Internal variables used for text direction$global-left: if($global-text-direction == rtl, right, left);$global-right: if($global-text-direction == rtl, left, right);
So, u can mark my comment as helpful :D
 

No. I meant $default-float and $opposite-direction. :PE.g. you can find those variables around 150 times in Foundation 5 SCSS. 

It was useful in multilanguage sites. So I didnt have to duplicate your layouts for providing both direction styles. But ok, I will create something similar and use it in my projects. :)
OFF:something wrong with registrating. I had to re register yesterday. And for the same e-mail today too. :/
 
 

Unfortunatelly the SASS compiler trims at 5 maximum digits, although chrome seemes to have some rounding differences with 5 or 6 digit
