      ndarray.itemsize the size in bytes of each element of the array. For example, an array of elements of type float64 has itemsize8 (=64/8), while one of type complex32has itemsize4 (=32/8). It is equivalent to ndarray.dtype.itemsize. ndarray.data the buffer containing the actual elements of the array. Normally, we won’t need to use this attribute

      Abstract It is proposed to add to the C++ standard optional floating-point typedef s having specified widths.The optional typedef s include float16_t, float32_t, float64_t, float128_t, their corresponding least and fast types, and the corresponding maximum- width type. These are to conform with the corresponding specifications of binary16, binary32, binary64, and binary128 in

      Here, float64 is a numeric type that NumPy uses to store double-precision (8-byte) real numbers, similar to the float type in Python. When used with an array, the len function returns the length of the first axis: ... One can convert the raw data in an array to a binary string (i.e., not in human-readable form) using the tostring function. The ...
