If we're going to have convenience multiples of PI, they should be a) non-ideological, and b) include more than one (PI/2 comes up a lot in vector math, for example).
Why not have: Math.PI Math.DPI //double pi Math.HPI //half pi Or perhaps we should just let people define their own constants. This does seem a bit silly.
