# Complex polynomial value calculation

The calculator evaluates polynomial value. The polynomial coefficients can be either real or complex.

A polynomial is defined by the coefficients array, which can be real or complex numbers. The first coefficient belongs to the highest degree term; the last one is the constant term. The number of coefficients automatically defines the polynomial degree. If your polynomial misses a term, just set zero as its coefficient. Both polynomial coefficient and sample variable value can be either real or complex. (For real number, enter zero in the imaginary part.)

The calculator can be used for equation solution checking. E.g. this one: Quartic equation or this: Cubic equation.
