In order to make numpy display float arrays in an arbitrary format, you can define a custom function that takes a float value as its input and returns a formatted string: In [1]: float_formatter = "{:.2f}".format.

NumPy (Num erical Py thon) is an open source Python library that’s widely used in science and engineering. The NumPy library contains multidimensional array data structures, such as the homogeneous, N-dimensional ndarray, and a large library of functions that operate efficiently on these data structures.
A standard double-precision floating-point value (what’s used under the hood in Python’s float object) takes up 8 bytes or 64 bits. Thus, this type is known in NumPy as float64. See Table 4.2 for a full listing of NumPy’s supported data types.

In this tutorial, you'll dive deep into working with numeric arrays in Python, an efficient tool for handling binary data. Along the way, you'll explore low-level data types exposed by the array module, emulate custom types, and even pass a Python array to C for high-performance processing.
