vitaut.net https://vitaut.net/posts/2026/complete-to-chars/ - libstdc++'s floating-point std::to_chars, every format and precision for float through long double, adds about 256 kB to a statically linked binary.

vitaut.net https://vitaut.net/posts/2026/yy-dtoa/ - Żmij, the binary-to-decimal conversion library I wrote about a few posts back, started as an optimized port of Schubfach.

vitaut.net https://vitaut.net/posts/2026/every-float/ - In my previous post about Żmij, a high-performance binary-to-decimal floating-point conversion library, I drew a small diagram of a rounding interval around a single floating-point value.

vitaut.net https://vitaut.net/posts/2025/faster-dtoa/ - There comes a time in every software engineer’s life when they come up with a new binary-to-decimal floating-point conversion method.

vitaut.net https://vitaut.net/posts/2025/to-chars/ - I was recently adding my Schubfach double-to-string conversion algorithm implementation to dtoa-benchmark and noticed that std::to_chars was notably missing from that benchmark.

vitaut.net https://vitaut.net/posts/2025/smallest-dtoa/ - Converting floating-point numbers to their shortest decimal representations has long been a surprisingly challenging problem.

vitaut.net https://vitaut.net/posts/2024/simple-dtoa/ - My previous blog post gained some attention on Hacker News (discussion), and as someone deeply interested in floating-point formatting, I couldn't ignore the following comment: It's kind of mindblowi…

vitaut.net https://vitaut.net/posts/2024/binary-size/ - The {fmt} formatting library is known for its small binary footprint, often producing code that is several times smaller per function call compared to alternatives like IOStreams, Boost Format, or, s…

vitaut.net https://vitaut.net/posts/2024/faster-cpp-compile-times/ - In this post I'll talk about bringing compile times of the {fmt} library on par with the C standard I/O library (stdio).

vitaut.net https://vitaut.net/posts/2023/print-in-cpp23/ - I just realized that 2023 is almost over and I haven't posted about the most important feature of C++23.
