+ 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'.
