/// @assertion The static type of an multiplicative expression is usually
/// determined by the signature given in the declaration of the operator used.
/// However, invocations of the operators *, % and ~/ of class int are treated
/// specially by the typechecker.
///   The static type of an expression e1 * e2 where e1 has static type int is
/// int if the static type of e2 is int, and double if the static type of e2 is
/// double.
///   The static type of an expression e1 % e2 where e1 has static type int is
/// int if the static type of e2 is int, and double if the static type of e2 is
/// double.
/// The static type of an expression e1 ~/ e2 where e1 has static type int is
/// int if the static type of e2 is int.
/// @description Checks special cases for static types of expressions
/// x * y, x % y, x ~/ y when x is int.
