  1. I'm sorry, that second reference was actually for the 3.5ULP variant. The 1 ULP is here: https://github.com/shibatch/sleef/blob/master/src/libm/sleef...

  2. …the sqrt is done on the input of the polynomial instead of the output. [1] https://sleef.org/ [2] https://github.com/shibatch/sleef/blob/master/src/libm/sleef...

  7. …portability layer. SLEEF is designed for C and thus has type suffixes which are rather verbose, see https://github.com/shibatch/sleef/blob/master/src/libm/sleef... But it offers a complete (more so than Highway's) libm. Eigen is similarly…

  9. …an abstraction layer (mostly for math). Instead of C++ function overloading, it uses type suffixes: https://github.com/shibatch/sleef/blob/master/src/arch/helpe...

  11. Not mentioned in the list of users is SLEEF ( https://github.com/shibatch/sleef ), which provides fast approximations for various elementary functions. (It generates coefficients for the approximations with mpfr) SLEEF itself is used by…
