Unit testing in 3.2/4.0 - Help?

Can someone who has SVN access look at the unit testing in the current SVN
trunk? I'm running into problems such as:

 [jeremy at jdesk tests]$ exu all.ex 
math.e:
  failed: deg2rad() #2. expected: 3.490658504 but got: 3.490658504
failed: deg2rad() #3. expected: {0.01745329252,3.385938749} but got:
  {0.01745329252,3.385938749}
  failed: rad2deg() #1. expected: 0.9998113525 but got: 0.9998113525
failed: rad2deg() #3. expected: {0.9998113525,28.64788976} but got:
  {0.9998113525,28.64788976}
  failed: exp() #2. expected: 9.974183 but got: 9.97418

254 tests run, 249 passed, 5 failed, 98% success

It has to do, I think, with long decimals. I've used printf() to print these
computed numbers: printf(1, "%.100f", {num}) .. and it seems the precision goes
to the 50th decimal point. Plugging in the value into the unit test to the 50th
value solved some of the mis-fires on failed tests, but not all of them.

How include/unittest.e determines if they are equal is not is by using the
equal() function. Nothing fancy.

To run the unit tests, simply change to the tests directory and run exu all.ex
(on unix) or exwc.exe all.ex on windows. Of course, have your euphoria
environment setup to use the new 3.2/4.0 instead of the production 3.1.

Thanks for any help with this.
