def _discovered_machar(ftype):

Create MachAr instance with found information on float types

def _fr0(a):

fix rank-0 --> rank-1

def _fr1(a):

fix rank > 0 --> rank-0

def _get_machar(ftype):

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 : class: Numpy floating point type class (e.g. np.float64)

Returns

ma_like : instance of MachAr or MachArLike: Object giving floating point parameters for ftype.

Warns

UserWarning: If the binary signature of the float type is not in the dictionary of known float types.
