IMAGINARY(ComplexNumber)

• is of the form .
• IMAGINARY(), returns the imaginary coefficient of a complex number

## Description

• This function gives the imaginary coefficient of a complex number.
• Complex number is a combination of real and an imaginary number.
• Imaginary number is a real number which is multiplied with the imaginary unit , where .
• When imaginary number is get adding to the real number , then it forms a complex number.
• Also when we are squaring the imaginary number , it will give the negative real number .
• For eg .
• We can use COMPLEX function to convert the real and imaginary coefficients to a complex number.
• A complex number is a imaginary number when the real part is zero.

## ZOS

• The syntax is to calculate IMAGINARY in ZOS Section is .
• is of the form .
• For e.g.,IMAGINARY("6-0.5i")
Imaginary

## Examples

1. =IMAGINARY("2+3i")=3
2. =IMAGINARY("4-5i")=-5
3. =IMAGINARY("3j")=3
4. =IMAGINARY("7")=0
