Absolute Value of Complex Numbers Calculator: A Comprehensive Guide

Introduction

The absolute value of a complex number is a measure of its magnitude or distance from zero in the complex plane. It is often denoted by the symbol $|z|$. The absolute value of a complex number $z = a + bi$ is defined as:

$$|z| = \sqrt{a^2 + b^2}$$

where $a$ and $b$ are the real and imaginary parts of $z$, respectively.
