<xtal-math>
I, <xtal-math>, am very well acquainted with matters mathematical.
I provide a web component wrapper around third party math libraries.
For the first one, this may be the world’s first web component defined via an iframe. Click here to see it in action. Note that it progressively renders. It is a basic calculator, based off the mostly css-based code-pen.
Yes, yes, a JS based version is also available: xtal-math-giana-pen-js.js.
Sincerely,
Major General
