Complex Numbers in p5

pwii

I want to explore some of the geometrical aspects of complex numbers through p5. What are some ways to go about this?

@pwii -- if you intend to represent the components of your complex numbers as x,y vectors, then use p5.Vector:

• https://p5js.org/reference/#/p5.Vector
• https://p5js.org/reference/#/p5/createVector

p5.js doesn't bundle any class to deal w/ complex numbers.
You're gonna need to find another library for it and use it together w/ p5.js.

I've done a quick search on GitHub and found 2:

1. https://GitHub.com/arian/Complex
2. https://GitHub.com/infusion/Complex.js

If you pick up library Complex, here's an "index.html" template for it:

<script async src=http://CDN.JSDelivr.net/npm/p5></script>
<script defer src=http://CDN.JSDelivr.net/npm/complex/lib/Complex.min.js></script>
<script defer src=sketch.js></script>

And for library Complex.js version:

<script async src=http://CDN.JSDelivr.net/npm/p5></script>
<script defer src=http://CDN.JSDelivr.net/npm/complex.js/complex.min.js></script>
<script defer src=sketch.js></script>

Notice though library Complex.js belongs to a much bigger 1 called Math.js:
http://MathJS.org/docs/datatypes/complex_numbers.html

If you prefer to get everything, this is the template for it: O:-)

<script async src=http://CDN.JSDelivr.net/npm/p5></script>
<script defer src=http://CDN.JSDelivr.net/npm/mathjs/dist/math.min.js></script>
<script defer src=sketch.js></script>

Sorry for the late response! This is everything I asked for :)! Where did you get the link for the mathjs library?

Where did you get the link for the Math.js library?

• Once I knew its NPM package name is mathjs from here: http://MathJS.org/download.html
• I've used CDN.JSDelivr.net's API syntax to navigate that NPM package: http://www.JSDelivr.com
  http://CDN.JSDelivr.net/npm/mathjs/
• And there, inside subfolder "dist/", I've found the Math.js library: "math.js" or "math.min.js"
  http://CDN.JSDelivr.net/npm/mathjs/dist/
