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 /slower/ than the 'Text' versions;
    roughly half the speed.  (This seems to be due to the cost of
    allocating 'ByteString' values via @malloc@.)
    .
    Builder versions are slower on single value, but they are much faster on large number of values 
    (up to 50x 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'.
