MathJS in ionic 2

Can someone please help me how to use mathjs in ionic 2? I just don't get it imported to use, really don't know what to do.

In ionic 1 it was easy to load the library and use it, but not so in ionic 2.

Thanks!

Solution

  • try this

    npm install mathjs --save
npm install @types/mathjs --save-dev

    in Component:

    import * as math from 'mathjs'; // don't named as Math, this will conflict with Math in JS

    in some method:

    let rs = math.eval('cos(45 deg)');

    or you could using CDN:

    add this line into index.html

    <script src="https://cdnjs.cloudflare.com/ajax/libs/mathjs/3.9.1/math.min.js"></script>

    in Component:

    // other import ....;
declare const math: any;

    in some method:

    let rs = math.eval('cos(45 deg)');
