Basic math utils

Features

• Extend functions for float and double. e.g. Round, AlmostEqual, Limit.
• Compute characteristic of array or 2d-array, e.g. Bound, Scale.
• Methods for polar coordinates, e.g. Rotate, Distance, Near.
• Parse algebraic expression and calculate, e.g. parse "3 + 4 * 2 / ( 1 - 5 ) ^ 2 ^ 3" and return 3.5.

Usage

Convert color

using Aryth.Calculator;

var expression = "3 + 4 * 2 / ( 1 - 5 ) ^ 2";
var result = expression.Calculate();
// result = 3.5

Bound of array

using Aryth.Bounds;

var samples = new[] { "foo", "bar", "zen", "16", "24", "32", "64" };
var (vector, bound) = vec.SoleBound();
// vector = [ NaN, NaN, NaN, 1, 2, 3 ]
// bound = ( 16, 64 )

Flop an array

using Aryth.Flopper;

var samples = new[] { "foo", "bar", "zen", "des" };
var flopper = FiniteFlopper<string>.From(samples);
Console.WriteLine($">> [next] {flopper.MoveNext()} {flopper.Current}"); // >> [next] True bar
Console.WriteLine($">> [next] {flopper.MoveNext()} {flopper.Current}"); // >> [next] True des
Console.WriteLine($">> [next] {flopper.MoveNext()} {flopper.Current}"); // >> [next] True foo
Console.WriteLine($">> [next] {flopper.MoveNext()} {flopper.Current}"); // >> [next] True zen
Console.WriteLine($">> [next] {flopper.MoveNext()} {flopper.Current}"); // >> [next] False zen
