type t = [ `Float64 | `Object ] Obj.tval of_pyobject : Py.Object.t -> tval to_pyobject : [> tag ] Obj.t -> Py.Object.tval create : ?x:Py.Object.t -> unit -> tDouble-precision floating-point number type, compatible with Python `float` and C ``double``. Character code: ``'d'``. Canonical name: ``np.double``. Alias: ``np.float_``. Alias *on this platform*: ``np.float64``: 64-bit precision floating-point number type: sign bit, 11 bits exponent, 52 bits mantissa.
val __getitem__ : key:Py.Object.t -> [> tag ] Obj.t -> Py.Object.tReturn selfkey.
val fromhex : string:Py.Object.t -> [> tag ] Obj.t -> Py.Object.tCreate a floating-point number from a hexadecimal string.
>>> float.fromhex('0x1.ffffp10') 2047.984375 >>> float.fromhex('-0x1p-1074') -5e-324
val hex : [> tag ] Obj.t -> Py.Object.tReturn a hexadecimal representation of a floating-point number.
>>> (-0.1).hex() '-0x1.999999999999ap-4' >>> 3.14159.hex() '0x1.921f9f01b866ep+1'
val is_integer : [> tag ] Obj.t -> Py.Object.tReturn True if the float is an integer.
newbyteorder(new_order='S')
Return a new `dtype` with a different byte order.
Changes are also made in all fields and sub-arrays of the data type.
The `new_order` code can be any from the following:
* 'S' - swap dtype from current to opposite endian * '<', 'L' - little endian * '>', 'B' - big endian * '=', 'N' - native order * '|', 'I' - ignore (no change to byte order)
Parameters ---------- new_order : str, optional Byte order to force; a value from the byte order specifications above. The default value ('S') results in swapping the current byte order. The code does a case-insensitive check on the first letter of `new_order` for the alternatives above. For example, any of 'B' or 'b' or 'biggish' are valid to specify big-endian.
Returns ------- new_dtype : dtype New `dtype` object with the given change to the byte order.
val to_string : t -> stringPrint the object to a human-readable representation.
val show : t -> stringPrint the object to a human-readable representation.
val pp : Format.formatter -> t -> unitPretty-print the object to a formatter.
