tests pass, but results don't match !?

[Daniel Rohe]

I've compiled gsl-0.8 on SuSE-7.1 and apparently all tests pass.
looking quickly over the results I found e.g. the following:


PASS: zgbmv(case 809) real (0.751079 observed vs 0.75108 expected)
PASS: plain, tsuda function, 2d, abserr[7] vs sd (0.00995764 observed vs
0.00726095 expected)
PASS: miser, product, 3d, abserr[5] vs sd (0.00905003 observed vs
0.00890616 expected)
PASS: vegas, product, 2d, result[7] (0.9999 observed vs 1 expected)
PASS: vegas, product, 2d, abserr[7] (obs 0.000233065 vs exp 0.01)


Although these differences are not necessarily relevant, I don't have a
really good feeling about this!

Maybe someone can tell me that I don't need to worry about it.

Cheers,
