IMAGINARY(ComplexNumber)
- is of the form .
- IMAGINARY(), returns the imaginary coefficient of a complex number
is of the form 
.
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.
, where 
.
is get adding to the real number 
, then it forms a complex number.
.
.ZOS
- The syntax is to calculate IMAGINARY in ZOS Section is .
- is of the form .
- For e.g.,IMAGINARY("6-0.5i")
.
Examples
- =IMAGINARY("2+3i")=3
- =IMAGINARY("4-5i")=-5
- =IMAGINARY("3j")=3
- =IMAGINARY("7")=0
