var (
	E  = rnt.NewFloat(math.E)
	Pi = rnt.NewFloat(math.Pi)
)

Mathematical constants.

var Ceil = rnt.NewSimpleFunction("Ceil",
	[]string{"f"},
	func(args []rnt.Object) rnt.Object {
		f := args[0].(rnt.Float).Value()
		return rnt.NewInt(int(math.Ceil(f)))
	})

Ceil wraps math.Ceil.

var Log = rnt.NewSimpleFunction("Log",
	[]string{"f"},
	func(args []rnt.Object) rnt.Object {
		f := args[0].(rnt.Float).Value()
		l := math.Log(f)
		if math.IsNaN(l) || math.IsInf(l, 0) {
			panic(rnt.RaiseType(rnt.ValueErrorType, "math domain error"))
		}
		return rnt.NewFloat(l)
	})

Log wraps math.Log.

var MaxUInt = rnt.NewInt(int(^uint(0) >> 1))

MaxUInt is the bigest unsigned integer value representable on the current platform.
