How it works
Convert a complex number to magnitude and phase.
THE CALCULATIONmagnitude = √(a²+b²); phase = atan2(b,a)
Using this calculator
Enter real part, imaginary part. magnitude = √(a²+b²); phase = atan2(b,a).
What to keep in mind
Finite real numbers unless a complex or exact-integer result is specified. Outputs are rounded for display. Matrix calculations use floating-point arithmetic.
Frequently asked questions
Are my entries saved?

Why are results rounded?
The display is rounded for readability. Calculations use unrounded intermediate values. An estimate should not be interpreted as an exact measurement.
