Chi-Squared p-value calculation without using a chart [algorithm]

I'm trying to implement a Chi-Square test in combination with Marascuilo's procedure in JavaScript.

The hardest part about this is calculating the p-value for the Chi-Squared test. There are many calculators out there but I don't want to just plug in numbers, I want to know the math behind them.

This calculation in C looks like exactly what I'm looking for (besides needing to translate it to javascript), but the magic numbers make it hard to follow what is being computed.

On a higher level, what is the algorithm for calculating Chi-Squared p-value without using a chart?
