Detailed Description

The gray_tools namespace exposes some tools for converting to and from the common gray code.

Function Documentation

template<typename T> T bin_to_gray (  const T &    i_value )

bin_to_gray converts any integer POD type from a binary (2s complement for signed numbers) to the run-of-the mill gray code commonly found.

template<typename T> T gray_to_bin (  T    value )

gray_to_bin computes the gray binary code given the gray code value. Even though this function exists, it is far more appropriate to use class gray_code below as this will render code more readable and far less prone to error. Parameters: value  contains the value to be converted.
