Introduction

What is ghc-double-conversion

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 <https 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’.
