IMREAL(z)

• $z$ is the complex number is of the form $x+iy$

Description

• This function gives the real coefficient of the complex number.
• IMREAL(z), $z$ is the complex number is in the form of $x+iy$
• where $x$ & $y$ are the real numbers. $i$ imaginary unit. $i={\sqrt {-1}}$.
• The complex number $z=x+iy$ can be identified by $(x,y)$ in the complex plane.
• Here $x$ is called real part and $y$ is the imaginary part of $z$.
• This function shows the value of the real part of $z$.
• A complex is said to be purely imaginary when $x=0$ and it is a real number when $y=0$.
• We can use COMPLEX function to convert real and imaginary number in to a complex number.

Examples

1. =IMREAL("3+4i") = 3
2. =IMREAL("-5+6i") = -5
3. =IMREAL("8") = 8
4. =IMREAL("-2i") = 0
