Double Interpolation

Your data is laid out as below:

p	y1	y	y2
x1	q11		q12
x		p
x2	q21		q22

which is run through the equation:

$p = \frac{x_{2} - x}{x_{2} - x_{1}} (\frac{y_{2} - y}{y_{2} - y_{1}} q_{11} + \frac{y - y_{1}}{y_{2} - y_{1}} q_{12}) + \frac{x - x_{1}}{x_{2} - x_{1}} (\frac{y_{2} - y}{y_{2} - y_{1}} q_{21} + \frac{y - y_{1}}{y_{2} - y_{1}} q_{22})$ = 3100.2

This should output 3100.2.
