|

A library that performs fast, accurate conversion between double
|
||||
precision floating point and text.
|
||||
|
||||
This library is implemented as bindings to the C++ double-conversion
|
||||
library written by Florian Loitsch at Google:
|
||||
https://github.com/floitsch/double-conversion.
|
||||
|
||||
The Text versions of these functions are about 30 times faster than the
|
||||
default show implementation for the Double type.
|
||||
|
||||
The ByteString versions are slower than the Text versions; roughly half
|
||||
the speed. (This seems to be due to the cost of allocating ByteString
|
||||
values via malloc.)
|
||||
|
||||
As a final note, be aware that the bytestring-show package is about 50%
|
||||
slower than simply using show.

# 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.
