Complex Number Calculator

v1.1.1

Perform arithmetic on complex numbers including modulus, argument, conjugate, and powers.

Performs arithmetic on complex numbers (a + bi) — addition, subtraction, multiplication, division, modulus, argument, conjugate, and powers — with Cartesian and polar form display.

How to use
  • →Enter complex numbers in a+bi form (e.g. 3+4i or -2-1i).
  • →Select the operation; the result is shown in both Cartesian (a+bi) and polar (r∠θ) form.
  • →Use the conjugate and modulus buttons to get related values without setting an operation.

Format: a+bi — e.g. 3+4i, -1-2i, 5, 2i
