This is how Kernel#{Array,String,Float,Integer,Hash,Rational} work.
BigDecimal and Complex instances are always frozen, so this should
not cause backwards compatibility issues for those. Pathname
instances are not frozen, so potentially this could cause backwards
compatibility issues by not returning a new object.
Based on a patch from Joshua Ballanco, some minor changes by me.
Fixes [Bug #7522]
Implement Complex#<=> so that it is usable as an argument when
calling <=> on objects of other classes (since #coerce will coerce
such numbers to Complex). If the complex number has a zero imaginary
part, and the other argument is a real number (or complex number with
zero imaginary part), return -1, 0, or 1. Otherwise, return nil,
indicating the objects are not comparable.
Fixes [Bug #15857]
Cannonicalize resultant real and imaginary parts when complex number
divided by non-complex number.

This fixes the incompatibility (maybe unintentionally) introduced by
removal of `#ifndef PRESERVE_SIGNEDZERO` guards in f_add, f_mul, and
f_sub functions in r62701. [Bug #15491] [ruby-core:90843]

* complex.c (rb_complex_new_polar): renamed with _new to clarify
that it creates a new instance, but is not an instance method.
* complex.c (rb_complex_polar): deprecated.

allocating intermediate Complex objects, and avoid unexpected
NaNs.

returns more precise value in right angle cases.

form.

for imaginary part, in documentation for Complex#{finite?,infinite?}.

Support `exception:` keyword argument in `Kernel#Complex()`.
If `exception:` is `false`, `Kernel#Complex()` returns `nil` if the given
value cannot be interpreted as a complex value.
The default value of `exception:` is `true`.
This is part of [Feature #12732].

Fixnums can be compared by object values themselves only.
Addition/subtraction/mulplication of fixnum 0 do not affect the
sign.
