Electronics: Opamp gain calculator

This calculator determines the output voltage and gain for an op-amp, given it's resistor values, and input voltage.
Non inverting: Gain (Av) = 1 + R2 / R1

R1	(KOhms)
R2 (Rf)	(KOhms)
Input (Vin)	(V)
V+	(V)
V-	(V)
Results
Vout	(V) Output is clipped.
Gain (non-inverting)	(Vout/Vin)

Inverting: Gain (Av) = -R2 / R1

R1	(KOhms)
R2 (Rf)	(KOhms)
Input (Vin)	(V)
V+	(V)
V-	(V)
Results
Vout	(V) Output is clipped.
