Comment (by gdt):

 Are we sure the tests are looking for a close value as a double, vs exact
 bits, and that we aren't comparing the value obtained with extended
 precision doubles (which are more than IEEE754, common on x86) vs standard
 precision doubles (typical on everything that isn't x86 and isn't vax).
