Introduction Link to heading Varint is a widely recognized technique used for compressing integer streams. Essentially, it suggests that it can be more efficient to encode a number using a variable-length representation instead of a fixed-size binary representation. By removing leading zeros from the binary number, the overall representation size can be reduced. This technique works particularly well for encoding smaller numbers. In this article, I provide a brief introduction and rationale for ...

"12.5" (one two dot five) and return a 64-bit double-precision floating point number like 12.5 (twelve point five). Some numbers (like 12.3) aren’t exactly representable as an f64 but ParseNumberF64 still has to return the best approximation. In March 2020, Daniel Lemire published some source code for a new, fast algorithm to do this, based on an original idea by Michael Eisel. Here’s how it works. Preliminaries Fallback Implementation First, a caveat. The Eisel-Lemire algorithm is very ...
