Explore our free online comprehensive **complex number calculator**. This powerful scientific complex number calculator can evaluate and simplify mathematical expressions containing real and imaginary numbers in any form. With user-friendly features, you can input complex numbers in both rectangular ** a+bi** and polar

**forms directly into your expressions. It can handle complex number expressions ranging from simple forms like (1+2i) - (3-4i) to more intricate forms like sin(1+2i)/ln(3+4i) + atan(1+3i) - 4∠(1.8). The calculator converts the results to both standard and various modular forms, such as polar.**

`r∠(θ)`

## Seamless Rectangular and Polar Conversion

The **complex number calculator** performs **conversions between rectangular and polar forms** internally, and can display the results in various forms, including **rectangular** (**standard**) ** a+bi** and

**polar**(

**phasor**)

**, and other**

`r∠(θ)`

**modular**forms.
