realpart
Returns the real component of a complex expression.
Nerdamer expands supported algebraic structure and separates known real and complex factors. Expressions whose complex component cannot yet be resolved can remain under realpart(...).
Examples
These examples use Nerdamer Notation.
Extract the real component of a numeric complex value.
realpart(3+2*i)
// → 3Expand a symbolic complex product and collect its real component.
realpart((a+b*i)*(c+d*i))
// → a*c-b*dInterfaces
