currency.js VS Complex.js

this lib is very good https://currency.js.org/

However, there are always great libraries that the community develops to support missing features, such as dinero.js, currency.js, and numeral.js.

it's not like there are libraries for this exact use case, no way!

I personally use this function from currency.js for formatting currency. You can either extract it if you feel comfortable doing that, or just use the whole library; it isn't that big.

The background for this is that I'm using Node-RED to acquire data from a .csv file. Then, I am transferring it to a database where before that I would need to flip the time trace to the frequency domain via a pwelch. That way I can store the time trace and the frequency domain data. Currently what I am doing is using the Complex.js library found here: https://github.com/infusion/Complex.js. After that, I just use a very simple DTFT to get the frequency domain. However, I want to add some overlapping, window length and zero padding to my transformation, and this is where I think it would be easier to just a pwelch. I'm wondering if there is an simple way of implementing this. Otherwise I would have to have to look into a window library and create some sort of overlap using DTFT or another fourier transform technique.
