IMREAL (ComplexNumber)

• is of the form .
• IMREAL(),returns the real coefficient of a complex number.

## Description

• This function gives the real coefficient of the complex number.
• In , ComplexNumber 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 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.

## ZOS

• The syntax is to calculate real coefficient of the complex number in ZOS is .
• is of the form .
• For e.g.,IMREAL(IMSUM("2+3i","1-9i"))

## Examples

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