#ReleaseThursday #OpenSourceXmas A little present (to some of you)... Been meaning to release these recent additions before the holidays, but only getting around to it now. The most important new things are these:

https://thi.ng/units now includes a Lisp-like formula DSL to combine, calculate and convert quantities and units in a much concise manner than via the normal TypeScript API (see attached examples)

https://thi.ng/pixel-io-tiff is a new package (only 2.6KB) to provide TIFF image format parsing and EXIF/GPS metadata extraction (without having to parse the image fully). Also includes format conversions for https://thi.ng/pixel buffers (grayscale 8/16bit, RGB 24/32bit), but only supports most common TIFF features (e.g. tiles, strips, uncompressed or deflate). Supports multiple sub-images... Write support will be released early next year

https://thi.ng/math now has conversions to/from fractions, using "continued fractions" for best possible precision (also includes recursion-free implementations of GCD & LCM).

https://thi.ng/binary now provides `DATAVIEW`, a JS-native DataView-like API tailored for using `Uint8Array` or vanilla JS numeric arrays (assuming the array contains u8 values) and accessors for signed/unsigned 8-64bit word sizes and little/big endian ordering.

See main #ThingUmbrella readme for other recent updates:
