Again, Thanks!

You're welcome. Also, you posted these two results:

Quote:Example 1
=========

To calculate the integral of 1/x from 1 to 2 (which is equal to ln(2)):
[...]
The program displays 0.69315 as the value of the integral,

Example 2
========

To calculate the integral of exp(-x)*x^0.8 from 0 to inifinity (which is equal to gamma(1.8)):
[...]
The program displays 0.93138 as the value of the integral.

Both were posted as 5-digit values. Could you please post these two results to full 10-digit accuracy ? It would be necessary to gauge the correctness of your program/data in order to detect any further errors and, again, for people using your program to check that they do exactly obtain your results to full 10-digit precision.
