Imaginary part of complex number

The imaginary part calculator allows you to calculate online the imaginary part of a complex number.


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.

Syntax :

imaginary_part(z), z is a complex number.


Examples :

imaginary_part(`1+7i`), returns 7
