text ‹
  operations ‹div› and ‹mod› are built-in in Boogie, but
  a particular semantics due to different interpretations in
  languages. We assume that each application comes with a
  axiomatization.

axiomatization
  boogie_div :: "int ==> int ==> int" (infixl ‹div'_b› 70) and
  boogie_mod :: "int ==> int ==> int" (infixl ‹mod'_b› 70)
