The hexstring is a string of hexadecimal characters. It can be of any length. Each hexadecimal character is converted to a string of four binary digits. You can optionally include blanks in hexstring (at byte boundaries only, not leading or trailing) to aid readability; they are ignored.

The returned string has a length that is a multiple of four, and does not include any blanks.

If hexstring is null, the function returns a null string.

Examples

X2B('C3')        ->  '11000011'
X2B('7')         ->  '0111'
X2B('1 C1')      ->  '000111000001'

You can combine X2B with the functions D2X and C2X to convert numbers or character strings into binary form. For example:

X2B(C2X('C3'x))  ->  '11000011'
X2B(D2X('129'))  ->  '10000001'
X2B(D2X('12'))   ->  '1100'
