Member Function Documentation

encodingWidth()

unsigned BEMTools::encodingWidth ( unsigned  encoding, unsigned  extrabits  )

static

Returns bit width required by the encoding and extrabits combination.

Note

encoding value of zero translates to width of zero.

                                                             {
    return MathTools::bitLength(encoding) + extrabits;
}

extrabits()

unsigned BEMTools::extrabits ( unsigned  encoding, unsigned  width  )

static

Calculates the extra bits (zeroes) of the given encoding.

For example:

*  (encoding, width) = (3, 5) ->  |00011| -> return 3.
* 

Parameters

encoding	The encoding value.
width	The number of bits the encoding occupies. Must be at least or more than required bits needed for the value. Must greater than 0.

    assert(width > 0);
    return width - MathTools::bitLength(encoding);
