Real part of complex number

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


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

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

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

The complex numbers calculator can also determine the real part of a complex expression. To calculate the real part of the following complex expression z=`(1+i)/(1-i)`, enter real_part(`(1+i)/(1-i)`) or directly (1+i)/(1-i), if the button real_part already appears, the result 0 is returned.

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

Syntax :

real_part(z), z is a complex number


Examples :

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