Class np.dtypes

Namespace

NumSharp

Assembly

NumSharp.dll

numpy.dtypes (NEP 56 / NumPy 1.25+): the DType CLASSES — np.dtypes.Float64DType is type(np.dtype('f8')). Each member is the live DTypeMeta singleton; its Instantiate() is NumPy's class call (Int8DType() → dtype('int8'); DateTime64DType() raises the "Preliminary-API … can only be instantiated using np.dtype(...)" TypeError), and Meta is type(dtype).

Remarks

Names and aliases are NumPy 2.4.2's numpy.dtypes.all: ByteDType/UByteDType for int8/uint8, ShortDType/UShortDType for int16/uint16, IntDType/UIntDType for int32/uint32, LongLongDType/ULongLongDType for int64/uint64, and the platform-dependent LongDType/ULongDType (C long: 32-bit on Windows and 32-bit hosts, 64-bit on LP64 Unix). LongDoubleDType and CLongDoubleDType alias the 64-bit float / complex classes — NumSharp has no extended precision, exactly as NumPy's win-amd64 build. The classes NumPy has and NumSharp does not (Complex64DType, StrDType, BytesDType, StringDType, ObjectDType, VoidDType) are absent rather than stubbed; DecimalDType and CharDType are NumSharp-only.
