emmy.complex
This namespace provides a number of functions and constructors for working with [[Complex]] numbers in Clojure and ClojureScript, and installs [[Complex]] into the Emmy generic arithmetic system.
For other numeric extensions, see emmy.ratio
and [[emmy.numbers]].

complexclj/s
(complex c)(complex re im)Returns a [[Complex]] number with the supplied real part re and imaginary
part im. im defaults to 0.
Returns a [[Complex]] number with the supplied real part `re` and imaginary part `im`. `im` defaults to 0.
complex?clj/s
(complex? a)Returns true if a is an instance of [[Complex]], false otherwise.
Returns true if `a` is an instance of [[Complex]], false otherwise.
parse-complexclj/s
(parse-complex c)Used as a data reader. In Clojure, we could get away with just using the constructor above, but in ClojureScript we need to act as a macro to delay evaluation of the constructor.

roundclj/s
(round z)Generates a Gaussian integer
from the complex number z by rounding the real and imaginary components of
z to their nearest integral values. (Note: the use of cast-to-double is
unfortunate here, as complex numbers can now contain exact fractions, and
we'd want a nearest integer generic function for those)
