An extension of the familiar real number system in which all numbers are expressed as a sum of a real part and an imaginary part. Imaginary numbers are real multiples of the imaginary unit (the square root of ), often written in mathematics or in engineering. Python has builtin support for complex numbers, which are written with this latter notation; the imaginary part is written with a suffix, e.g., 3+1j. To get access to complex equivalents of the math module, use cmath. Use of complex numbers is a fairly advanced mathematical feature. If you're not aware of a need for them, it's almost certain you can safely ignore them.

A number that can be written in the form a ++ b where a and b are real numbers and

A number formed of two parts, so called real and imaginary parts, both of which are real number

Mathematics. Any number of the form + bj, where and are real numbers and is an imaginary number whose square equals -1; and represents the real part (e.g., the resistive effect of a filter, at zero phase angle) and represents the imaginary part (e.g., the reactive effect, at 90 degrees phase angle).

Comprised of a real and imaginary part.

A number that is the sum of a real number and an imaginary number.

In mathematics, a complex number is a number of the form
