Functions

distance

fun distance(aX: Float, aY: Float, bX: Float, bY: Float): Float

fun distance(aX: Int, aY: Int, bX: Int, bY: Int): Float

round

fun round(d: Float): Int

Ends up being a bit faster than the platform rounding implementation. This merely rounds its argument to the nearest int, where x.5 rounds up to x+1. Semantics of this shortcut differ slightly from platform rounding in that half rounds down for negative values. -2.5 rounds to -3, not -2. For purposes here it makes no difference.
