Properties of a Python
floatcan be requested viasys.float_info. It returns information such as max/min value, max/min exp value, etc. These properties can potentially be used to calculate the byte size of a float. I never encountered anything else than 64 bit, though, on many different architectures.The items of a NumPy array might have different size, but you can check their size in bytes by
a.itemsize, whereais a NumPy array.
