Complex numbers calculator. A complex number is an ordered pair of two real numbers (a, b). a is called the real part of (a, b); b is called the imaginary part of (a, b). To represent a complex number, we use the algebraic notation, z = a + ib with i 2 = -1. The complex number online calculator, allows to perform many operations on complex numbers.

If you want to find out the possible values, the easiest way is to go with De Moivre's formula. Our calculator is on edge because the square root is not a well-defined function on a complex number. We calculate all complex roots from any number - even in expressions: sqrt(9i) = 2.1213203+2.1213203i sqrt(10-6i) = 3.2910412-0.9115656i

To work out an approximate answer to a complex calculation we estimate. To estimate we round the numbers in the calculation to numbers that make the calculation easier This is usually one significant figure (but it does not have to be). Example 1: Estimate 4.13 × 28.1 0.53 To estimate the answer we need to round the numbers.
