| /* test66: test a whole bunch of basic comparisons.
 | |
|  *
 | |
|  * this test can be used both to generate test cases and run the test
 | |
|  * case. all the results to be computed are in myresults[] on each iteration.
 | |
|  * invoke the test with an argument, e.g. "./test66 gen" to generate 
 | |
|  * test66expected.h. then recompile, and run the result. so all you
 | |
|  * have to do to add a (integer-valued) test expression as a function
 | |
|  * of an int, float or double, is increase SUBRESULTS, add the expression
 | |
|  * to myresults[], and regenerate the desired results file.
