Fast_float is a C++ header-only library to parse doubles using SIMD instructions. The purpose is to speed up sorted sets and other commands that use doubles. A single-file copy of fast_float is included in this repo. This introduces an optional dependency on a C++ compiler. The use of fast_float is enabled at compile time using the make variable `USE_FAST_FLOAT=yes`. It is disabled by default. Fixes #1069. --------- Signed-off-by: Parth Patel <661497+parthpatel@users.noreply.github.com> Signed-off-by: Parth <661497+parthpatel@users.noreply.github.com> Signed-off-by: Madelyn Olson <madelyneolson@gmail.com> Signed-off-by: Viktor Söderqvist <viktor.soderqvist@est.tech> Co-authored-by: Roshan Swain <swainroshan001@gmail.com> Co-authored-by: Madelyn Olson <madelyneolson@gmail.com> Co-authored-by: Viktor Söderqvist <viktor.soderqvist@est.tech>
