====== RSHIFT() ======

//Since version 2.1//

Syntax:

  rshift!(<byte expression> [, <byte positions>])
or
  rshift(<int expression> [, <byte positions>])
  
The ''RSHIFT()'' function shifts each bit in //expression// to the right by the number of //positions// and returns the result of the operation.

The second argument can be omitted and it defaults to 1.

Warning: passing //positions// bigger than 127 will lead to undefined results.

===== Performance tip =====

Shifting the bits to the left is equivalent to dividing by powers of two, however much faster. Example:

  rem -- this is slow
  x = 364
  y = x / 4
  
  rem -- this is fast
  x = 364
  y = rshift(x, 2)
