| '''Summary'''
|Returns an {{Code|xs:base64Binary}} created by padding the input with {{Code|$size}} octets in front of the input. If {{Code|$octet}} is specified, the padding octets each have that value, otherwise they are zero.<br/>If the value of {{Code|$in }} is the empty sequence, the function returns an empty sequence.

| '''Summary'''
|Decodes binary data as a string in a given {{Code|$encoding}}.<br/>If {{Code|$offset}} and {{Code|$size}} are provided, the {{Code|$size}} octets from {{Code|$offset}} are decoded. If {{Code|$offset}} alone is provided, octets from {{Code|$offset}} to the end are decoded.If the value of {{Code|$in }} is the empty sequence, the function returns an empty sequence.

| '''Summary'''
|Shifts bits in binary data.<br/>If {{Code|$by}} is zero, the result is identical to {{Code|$in}}. If {{Code|$by}} is positive then bits are shifted to the left. Otherwise, bits are shifted to the right. If <code>|$by|</code> is greater than the bit-length of {{Code|$in}} then an all-zeros result is returned. The result always has the same size as {{Code|$in}}. The shifting is logical: zeros are placed into discarded bits. If the value of {{Code|$in }} is the empty sequence, the function returns an empty sequence.
