description:
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:
<http://code.google.com/p/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'.
