+The fast_float library provides fast header-only implementations for
+the C++ from_chars functions for float and double types. These
+functions convert ASCII strings representing decimal values (e.g.,
+1.3e10) into binary types. We provide exact rounding (including round
+to even). In our experience, these fast_float functions many times
+faster than comparable number-parsing functions from existing C++
+standard libraries.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
