const_math 1.0.3

A package providing compile time math functions, not optimized for run time calculation.

This package includes several "constable math functions" that can be called at compile-time which dart:math mostly cannot, returning const double, and can be used as compile-time constant.

They are const constructors of extension type on double implements double, therefore can be used just like normal double, with almost 0 cost.

It is not and will not be optimized for run-time, if need a run time calculation, condider using 'dart:math' or other libraries.

Getting started

In pubspec.yaml, add

dependencies:
  const_math: ^1.0.2

and run the pub get. In the place you wish to use these functions,

import 'package:const_math/const_math.dart';

Usage

These are compile time math functions that dart math does not provide, implemented by extension type on double.

const mySinValue = ConstMath.sin(3);

If you think the name of extension type ConstMath is too wordy, you can do something like this.

typedef CM = ConstMath;
const seventhRoot2 = CM.rt7(2);

These values can also be passed as argument to other const constructors, or to another ConstMath function.

const sinOfSin1 = CM.sin(CM.sin(1));
