By not doing the unrepresentable conversions, since they seem to be undefined behavior and even gcc 12 is inconsistent with them

/* Note that these tests (specifically 1, 3a and 3b) fail when compiled with
|
|
* clang and optimzing due to difference between clang and gcc, and more
|
|
* interestingly, within clang itself: with optimization enabled, the entries
|
|
* marked with "undef?" produce 0x80000000 instead of 0, but with optimization
|
|
* disabled, the expected 0 is produced.
|
|
* Inspecting the results, it seems that clang sets negative floats and doubles
|
|
* to 0 when casting to unsigned long, but not consistently.
