A complex number is an imaginary number and it is not real. It is expressed as a combination of a real part and an imaginary part as

        a + i b      where
               1)  a and b are real numbers (rational or irrational).
               2)  i = √-1       or    i² = -1

The real number algebra is applied to complex numbers also. A real number cannot be equal to an imaginary number.

Examples are :       3 + 4 i    ,    -2.6 + i √2
