 ## Precision
 
-When looking at the computed styles in the inspector you may notice a pixel value like 17.999999px. This happens as a result of converting values from one type of unit to another in the functions. When the user is looking at the site, the whole site will still sit on baseline, just the baseline may differ slightly from one browser to another.
+Typesettings uses relative units and many of the values outputted are a result of dividing and multiplying. So a computed pixel value like 17.999999px will sometimes happen.
