Not necessary to be rude. You don't have to use it if it doesn't suit you.

You might be interested in BigDecimal if you want arbitrarily sized decimal numbers. This crate is for constant size, no allocation decimals; which does apply a limit to the size of numbers that can be handled.

Thanks folks! I've used this as an opportunity to update the readme to add a section calling out when this library may not be suitable and to highlight alternatives. Feel free to take a look and as always if something looks off or could be explained better then let me know (or open a PR).

In the meantime, I'll close this issue since there isn't anything actionable (other than readme clarification) that can be done.
