The complex data type has a type ID of 3.

Making Constants

One way to make complex constants is with this notation:

(a,b)

Where a and b are arbitrary expressions. It is translated to an expression in the following format:

(a)+(b)*i

This is the translation that literally happens in HPPPL; thus, type errors may occur in some cases.

Limits

Each part of a complex expression is bounded to the limits of a real. It follows the rules specified there.
