[Numpy-discussion] question about long doubles on ppc64el

[Thomas Caswell]

Folks,

Over at h5py we are trying to get a release out and have discovered (via
debian) that on ppc64el there is an apparent disagreement between the size
of a native long double according to hdf5 and numpy.

For all of the gorey details see: https://github.com/h5py/h5py/issues/817 .

In short, `np.longdouble` seems to be `np.float128` and according to the
docs should map to the native 'long double'.  However, hdf5 provides a
`H5T_NATIVE_LDOUBLE` which should also refer to the native 'long double',
but seems to be a 64 bit float.

Anyone on this list have a ppc64el machine (or experience with) that can
provide some guidance here?

Tom
