Calling Sequence



  output = Binary(theNumber)

Return Value



  output: A string array of 0s and 1s to be printed (normally), in a
                  binary representation of the number. The number is represented with
                  the highest bits on the left and the lowest bits on the right,
                  when printed with the PRINT command.

Arguments



  theNumber: The number for which the user wants a binary representation.
                  It must be BYTE, INT, or LONG.

Keywordrs



  COLOR: If this keyword is set, the binary representation always
                  contains 24 bits of output.
  SEPARATE: If this keyword is set, the output is separated with space
                  between each group of eight bits.

Example



  IDL> Print, Binary(24B)
          0 0 0 1 1 0 0 0
  IDL> Print, Binary(24L)
          0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 0
  IDL> Print, Binary(24L, /COLOR)
          0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 0
