imagpart
Returns the imaginary component of a complex expression.
Nerdamer expands supported algebraic structure and separates known real and complex factors. Purely real expressions return zero; unresolved complex functions can remain under imagpart(...).
Examples
These examples use Nerdamer Notation.
Extract the imaginary coefficient.
imagpart(3+2*i) // → 2
A plain real symbol has zero imaginary component.
imagpart(x) // → 0
