Math preprocessing bug

height: calc(100vh - 43px); turns into height: calc(57vh); what is not the same.

You can use calc(~"100vh - 43px") to solute this problem now. I will confirm which component caused the problem later

I have found a issue related to this problem: https://github.com/less/less.js/issues/1366 In short, calc is a keyword of less, less will calculate it. But many values can not be calculated, for example, 100% - 10px, 100vh + 3px, but less aslo will try to calculate it. So, if you do not want less compiler calculate it: If you do not use less variables in calc, use calc(~"100% - 40px") If you want to use less variables in calc, use calc(~"100% - @{foo}")

I will enable "Strict Math" option next version
