Maths module needs more methods

DrScott

The Maths module contains Atan2, but is lacking commonly-used mathematical methods such as Sin, Cos and Tan.

Hi @DrScott

Some methods are in Double class

Thank you. It’s kind of odd to have some trigonometric functions in Double and some in Maths.

Thanks, you’re right - that split was odd.

The original intent was that single-value maths methods could be called directly on numbers, e.g. angle.Sin() or (Maths.PI / 2.0).Cos(), while Maths.Atan2(y, x) lived on Maths because it needs two values.

That said, Maths.Sin(angle) / Maths.Cos(angle) / Maths.Tan(angle) is the shape many people naturally look for, so I’ve added shared aliases on the Maths module for the next release. Both styles will work:

Var angle As Double = Maths.PI / 4.0

Print(angle.Sin())
Print(Maths.Sin(angle))
