Summary

This chapter showed how to use two sets of functions from_chars - to convert strings into numbers, and to_chars that converts numbers into their textual representations.

The functions might look very raw and even C-style. This is a “price” you have to pay for having such low-level support, performance, safety, and flexibility. The advantage is that you can provide a simple wrapper that exposes only the needed parts that you want.

Extra Info: The change was proposed in: P0067.
