Complex canonicalizer for the constant atom
Complex2Real.constant_canon(expr, real_args, imag_args, real2imag)
An Expression object
A list of Constraint objects for the real part of the expression
A list of Constraint objects for the imaginary part of the expression
A list mapping the ID of the real part of a complex expression to the ID of its imaginary part.
A canonicalization of a constant atom, where the returned variables are the real component and the imaginary component in the Constant atom.
