Is there any use for finfo.machar? Can we just include that in the deprecation (i.e. make it a private variable if we still need it)?

Is there any use for finfo.machar?

There are a few MachAr attributes that are not exposed to finfo.
Some are available under a different name (xmin -> min), but others (ibeta) would have to be added.

In [11]: import numpy as np

In [12]: finfo_f8 = np.finfo(np.float64)
    ...: machar_f8 = np.MachAr(np.float64)

In [14]: set(dir(machar_f8)) - set(dir(finfo_f8))
Out[14]: 
{'_do_init',
 '_str_xmax',
 '_str_xmin',
 'epsilon',
 'huge',
 'ibeta',
 'irnd',
 'it',
 'ngrd',
 'title',
 'xmax',
 'xmin'}

Hmm, fair point. On some of these, I would be willing to just gamble that nobody uses them anyway, i.e. ibeta is always 2. Some seem like they might be interesting on weird platforms/settings (irnd or ngrd) though, I tend to trying getting rid of them, but not sure.

Ah well, let's give deprecating finfo.machar a shot.

Thanks Bas.
