* \brief Fast integer and floating-point numbers to string conversion
*
* This defines signed/unsigned integer, and 'double' to char buffer
* converters. The standard way of doing this is with "sprintf", however
* these functions are
* * guaranteed maximum size output
* * 5-20x faster!
* * Won't core-dump
