IMAGINARY(z)
- where 'z' is the complex number is in the form a+bi.
Description
- This function gives the imaginary coefficient of a complex number.
- Imaginary number is a real number which is multiplied with the imaginary unit i,where i=sqrt(-1).
- When imaginary number bi is get adding to the real number a, then it is form a complex number.
- Also when we are squaring the imaginary number bi, it will give the negative real number -b^2.
- For eg (5i)^2=-25.We can use COMPLEX function to convert the real and imginary coefficients to a complex number.
- A complex number is a imaginary number when the real part is zero.
Examples
- IMAGINARY("2+3i")=3
- IMAGINARY("4-5i")=-5
- IMAGINARY("3j")=3
- IMAGINARY("7")=0
