How to use Complex Number Calculator

Complex arithmetic uses real/imaginary pairs. Division scales the denominator before combining components to avoid avoidable overflow.

Enter first real component, first imaginary component, second real component, second imaginary component.
Check the model, units, and supported limits before calculating.
Run the tool, inspect the result, then copy or download it.

Bounded finite components; zero divisor rejected. Argument of a zero result is undefined. Output argument is in radians.
Runs locally. Numeric inputs are bounded; floating-point output is approximate and rounded to 12 significant digits. Unsupported or non-finite calculations produce an error.

Solve ax² + bx + c = 0, including repeated and complex roots, with a stable real-root formula.

Evaluate a real logarithm or power with explicit base and domain checks.

Find dot product, magnitude, displacement distance, angle, and three-dimensional cross product.

Calculate normalized low-pass, high-pass or notch coefficients, inspect requested frequency responses and filter a short zero-state sequence.
