New commits: commit 8933978710b8ef862222f53317cca73913e359a8 Author: Mike Kaganski <[email protected]> AuthorDate: Sun Sep 21 03:11:25 2025 +0500 Commit: Miklos Vajna <[email protected]> CommitDate: Wed Oct 1 09:49:37 2025 +0200 Replace dtoa with fast_float for faster string-to-float parsing fast_float implements C++17 from_chars for floating-point types, which is still unavailable even in the latest versions of compilers e.g. for macOS. It is maintained, unlike dtoa; it is said to be adopted as the from_chars implementation for gcc. It is header-only, which simplifies many things.
