Hello Barton,
Problem 302 is clear. The expected accurarcy has to be adjusted by a small
amount. I suggest to choose 2.0e-15.
But problem 140 is not evaluated. What is the numerical value of the expression
gamma(1/3)- 2.678938534707748 on your system?

(Maybe the test suite should set display2d to false.)
********************** Problem 140 ***************
Input:
