It appears to be about 2x faster than the current algorithm, and equally accurate over the range for which I have tried it. It also theoretically should be easier to vectorize as branches are only used for checking for over/underflow. Update base/special/exp.jl Co-authored-by: Jeff Bezanson <jeff.bezanson@gmail.com> Better subnormal numbers, constant usage, and more accurate Break r into a hi and lo part to get extra accuracy. Fix previous comit. Error matches gexp Switch to minimax polynomial from taylor polynomial. equally fast version with a smaller table. Uses a quartic which allows a smaller table. Performance is equal to slightly better, and accuracy is similar. fully working? fix markdown rendering (JuliaLang#37235) add another deprecated internal function for backwards compat (JuliaLang#36794) Remove unnecessary volatile on memcpy (JuliaLang#37221) This is a local bitcast of different size through memory and doesn't need to be volatile. This was introduced due to a typo in 8e4327c when the argument order changed and the old tbaa parameter was passed in as isvolatile. aysnchronous typos (JuliaLang#37264) use printf/exit instead of `jl_error` for "too many threads" (JuliaLang#37223) This is too early for `jl_error` to work. fix expm1 for Float32 (calling wrong libm function) actually fix expm1 re-add exp10 docs slightly extend upper range for Float32 arguments re-add exp doctest, remove redundant exp10 doctest maybe now placing it after use round instead of magic re-add magic with better explanation remove the typo Fix all numbers taking the slow path with range checking. Oops Fix 32 bit build. Use `:ℯ` instead of `float64 ℯ` no functional change but less hacky Update base/special/exp.jl Co-authored-by: jmert <2965436+jmert@users.noreply.github.com> Update base/special/exp.jl Co-authored-by: jmert <2965436+jmert@users.noreply.github.com> Update base/special/exp.jl Co-authored-by: jmert <2965436+jmert@users.noreply.github.com>
