The double-conversion package

[Tags: bsd3, library]

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:

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.
