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.
