IMREAL(z)
- is the complex number is of the form
Description
- This function gives the real coefficient of the complex number.
- IMREAL(z), is the complex number is in the form of
- where & are the real numbers. imaginary unit. .
- The complex number can be identified by in the complex plane.
- Here is called real part and </math>y</math> is the imaginary part of .
- This function shows the value of the real part of .
- A complex is said to be purely imaginary when and it is a real number when .
- We can use COMPLEX function to convert real and imaginary number in to a complex number.
Examples
- IMREAL("3+4i")=3
- IMREAL("-5+6i")=-5
- IMREAL("8")=8
- IMREAL("-2i")=0
