[issue16534] test_float failure on IA64 (HPUX)

[Mark Dickinson]

Mark Dickinson added the comment:

>From the buildbot configure output:

checking whether C doubles are little-endian IEEE 754 binary64... no
checking whether C doubles are big-endian IEEE 754 binary64... yes
checking whether C doubles are ARM mixed-endian IEEE 754 binary64... no
checking whether we can use gcc inline assembler to get and set x87 control word... no
checking for x87-style double rounding... yes

Judging by that, it'll probably be using the legacy float repr, since the configure script didn't find a way to set the FPU control word.

In that case this is just an overeager test: we expect 50 digits of accuracy but the system-supplied formatting only gives us 35.

But it would also be good to try to find a way to enable the short float repr on that box.
