I won't lie, this is not my favorite aspect, but the only way to do it is have numbers be represented as a string (e.g. "10.128") and use a library to manipulate them. The number type unfortunately just does not work.

Would you mind sharing details about this, and your experience?

I ask not to challenge you or critique, but i have a deep interest in fintech and love Typescript. The ability to use it for fintech would be great, i just assumed it'd be too clunky to be practical.

that seems ... really really risky
