Numi user tries to migrate Qalc here.

cloud service: 120
telecom: 100

Not the maintainer, but I looked into how this could be done, and it looks like it would require adding a custom operator to math.js which means adding it to parse.js as well

This might also be possible by using a regex to replace the : with a = before parsing with math.js

Here's an example of the regex

You can actually get pretty close to this already like this:

Is this close enough?

Closing this issue out since I believe using = is comparable to : from Numi. If this is an issue (other than a quick re-learning or re-mapping your brain to the different symbol from Numi) feel free to reopen this.
