Starter code:

.tcshrc_3340 Copy this file to your home area and rename it! Source code to measure machine precision with single precision numbers. Source code to integrate via simpson's rule. Source code to seed and generate some random numbers. Source code from gsl libraries to seed and generate random numbers. Code to demo that summing up is not the same as summing down! (Summing down is slightly more accurate.) GSL code that uses the QAGS algorithm for integration. Quite a beauty. GSL code that uses a new random seed every time it is run to produce different sequence of random numbers for every execution.
