subsection ‹Integer arithmetics›

text ‹
The operations ‹div› and ‹mod› are built-in in Boogie, but
without a particular semantics due to different interpretations in
programming languages. We assume that each application comes with a
proper axiomatization.

axiomatization
  boogie_div :: "int ⇒ int ⇒ int" (infixl "div'_b" 70) and
  boogie_mod :: "int ⇒ int ⇒ int" (infixl "mod'_b" 70)
