IMREAL(z)

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

Description

• This function gives the real coefficient of the complex number.
• MREAL(z), Where z is the complex number is in the form of "x+iy".i.e.
• 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
