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

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