Writing z = a + ib where a and b are real is called algebraic form of a complex number z :

- a is the real part of z;
- b is the
**imaginary part**of z.

When b=0, z is real, when a=0, we say that z is pure imaginary.

For **calculating conjugate** of the **complex number** following z=1+7i,
enter imaginary_part(`1+7i`) or directly 1+7i, if the
imaginary_part button already appears, the result 7 is returned.

The complex numbers calculator can also determine the imaginary part of a complex expression.
To **calculate the imaginary part** of the following complex expression z=`(1+i)/(1-i)`,
enter imaginary_part(`(1+i)/(1-i)`) or directly
(1+i)/(1-i), if the button imaginary_part already appears, the result 1 is returned.

With this function, the calculator allows the **online calculation of the imaginary part** of a **complex number**.

The imaginary_part function calculates online the imaginary part of a complex number.
