Greetings, and thanks so much!
In general, 5.47 introduced a few testsuite errors revolving around
floating point precision issues/error bounds like this. The GCL code
being exercised not only has to deal with 32/64 bit, but extended
precision hardware, notably the 80bit x68. Maxima's testsuite
Camm, it appears that the quadpack code has not changed, so if there's
any difference in Maxima, it would have to be outside of quadpack.
Maybe the default float type has changed from 64 bits to 80 bits or
vice versa? Only a guess; I don't know what else to suggest.
You could narrow the scope by t
