How to do bitwise AND in SML/NJ?

Question

Need it for a program I'm writing (repeated squaring to comput x^n). I can't seem to find the syntax for it, or if it is even supported.

Answer 1

They're available within the Word8 and Word structures.

let
  open Word8
  infix andb orb xorb notb << >> ~>>
in
  print (Word8.fmt StringCvt.BIN 0wxF)             (* 1111 *)
; print "\n"
; print (Word8.fmt StringCvt.BIN 0wxA)             (* 1010 *)
; print "\n"
; print (Word8.fmt StringCvt.BIN (0wxF andb 0wxA)) (* 1010 *)
; print "\n"
end
