Quick Start

Visit HeronTool's Complex (复数运算) tool. In the input field, you can enter a complex number in a+bi format, e.g., 3+4i or -2-5i. Scientific notation (like 1.2e3+4i) and polar form (like 5∠53.13°, after switching mode) are also supported. After entering, click the "Calculate" button, and the result will display instantly.

Core Operations

1. Basic Arithmetic: Enter two complex numbers A and B in the respective fields, choose an operation (add, subtract, multiply, divide), and the result will show in both algebraic and polar forms.
2. Advanced Functions: Use the "Conjugate", "Modulus", and "Argument" buttons to quickly get properties of a single number. For powers or roots, enter an exponent (integer or fraction), and the tool returns all principal values.
3. Precision Settings: In "Settings", adjust decimal places (0-10) and choose angle unit (degrees or radians) to suit engineering or mathematical needs.

FAQ

Q: Can I enter a complex number with a negative imaginary part?
A: Yes, enter 3-4i, and the tool will recognize it automatically.

Q: Is polar form more convenient for multiplication?
A: Absolutely. Switch to polar mode, input magnitude and angle, then multiplication becomes simple magnitude multiplication and angle addition.

Q: How to handle complex equations?
A: The tool supports numerical calculations, not solving equations directly. However, you can manually simplify first, then verify the result with the calculator.
