 from string representations. It offers at lot of flexibility with respect to
 the conversion format: shortest, fixed, precision or exponential
 representation; decimal, octal or hexadecimal basis; control over number of
 digits, leading/trailing zeros and spaces.

 The library consists of efficient conversion routines that have been
 extracted from the V8 JavaScript engine. The code has been refactored
 and improved so that it can be used more easily in other projects.
