Yes, like I said `1turn` equals 2π and hence `1pirad` = `0.5turn` = `180deg` = `200grad`. Although halving or doubling may seem like really simple steps, they’re really about as complex as multiplication or division by 180 or 200 conceptually. The idea and benefit of `pirad` is to be mixed with `rad` transparently, although it’s rare having to deal with an even radian value without π or 0 being a factor. It’s also simpler to relate to sources external to stylesheets where you may use the π symbol. -- GitHub Notification of comment by Crissov Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/309#issuecomment-231963454 using your GitHub accountReceived on Tuesday, 12 July 2016 07:45:22 UTC
