def _fr1(a): (source)

fix rank > 0 --> rank-0

def _get_machar(ftype): (source)

Get MachAr instance or MachAr-like instance

Get parameters for floating point type, by first trying signatures of various known floating point types, then, if none match, attempting to identify parameters by analysis.

Parameters
ftype:classNumpy floating point type class (e.g. np.float64)
Returns
instance of MachAr or MachArLikema_like - Object giving floating point parameters for ftype.
Warns
UserWarningIf the binary signature of the float type is not in the dictionary of known float types.
