%description
A library that performs fast, accurate conversion between 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>.

Now it can convert single precision numbers, and also it can create Builder,
instead of bytestring or text.

The 'Text' versions of these functions are about 30 times faster than the
default 'show' implementation for the 'Double' type.

The 'ByteString' versions are have very close speed to the 'Text' versions;

Builder versions (both for Text and Bytestring) are slower on single value, but
they are much faster on large number of values (up to 20x faster on list with
20000 doubles).

As a final note, be aware that the 'bytestring-show' package is about 50%
slower than simply using 'show'.
