110 Name:
111   binary
112 Purpose:
113   Returns the binary representation of a number of any numerical type.
114 Argument:
115   number   scalar or array of numbers (any numerical type)
116 Returns:
117   Byte array with binary representation of numbers.
118 Examples:
119   Binary representation of 11b:
120     IDL> print, binary(11b)
121     0 0 0 0 1 0 1 1
122   Binary representation of pi (x86: Little-endian IEEE representation):
123     IDL> print, format='(z9.8,5x,4(1x,8i1))', long(!pi,0), binary(!pi)
124      40490fdb      01000000 01001001 00001111 11011011 (x86 Linux)
125      0fdb4149      00001111 11011011 01000001 01001001 (Alpha OpenVMS)
126     IDL> print, format='(8(1x,8i0))', binary(!dpi)
127      01000000 00001001 00100001 11111011 01010100 01000100 00101101 00011000
128   Some first tests before type double was added:
129     print, format='(2a6,4x,2z9.8,4x,8z3.2)', $
130       !version.arch, !version.os, long(!dpi,0,2), byte(!dpi,0,8)
131       x86 linux     54442d18 400921fb     18 2d 44 54 fb 21 09 40
132     sparc sunos     400921fb 54442d18     40 09 21 fb 54 44 2d 18
133     alpha   vms     0fda4149 68c0a221     49 41 da 0f 21 a2 c0 68
134     (Beginning with IDL 5.1, Alpha VMS uses IEEE representation as well.)
135 Modification history:
136    19 Dec 1997  Originally a news posting by David Fanning.
137                       (Re: bits from bytes)
138    20 Dec 1997  "Complete" rewrite: eliminate loops.
139    22 Dec 1997  Bit shift instead of exponentiation, return byte
140      array, handle input arrays.
141      Think about double and complex types.
142    22 Sep 1998  Complete rewrite: reduce every numerical type to
143      single bytes. Check that big and little endian machines
144      return exactly the same results (if IEEE).
145    7 May 2003     Added newish data types, unsigned and long64.  BT</div>
