What you expected are From Base and To Base?

@chengxuncc I'm not sure what you mean, can you elaborate?

This translates between a decimal integer and a string, if that’s what you mean

I believe it's useful to have a dedicated method for this, as opposed to a roundabout recipe with multiple blocks

To add, this method using "To Base" and "From Hex" fails when the first byte is in the range 0x01 - 0x0f (only have 1 digit instead of 2).
It should be nice to having a way to handle this automatically.

Example:

Encoding: To Hex, From Base - CyberChef
Decoding (fails): To Base, From Hex - CyberChef

Hey! This pull request has gotten rather old and that's our fault. This project stopped being actively maintained for a while and it looks like your pull request has started to gather dust. Would you be able to update your branch to the latest version of CyberChef and we'll give it a review?

Looks like GH permanently closed this while trying to rename my branch 🤔 I'll open a new PR
