Submitted by Pranit Sharma, on December 27, 2022

NumPy is an abbreviated form of Numerical Python. It is used for different types of scientific operations in python. Numpy is a vast library in python which is used for almost every kind of scientific or mathematical operation. It is itself an array which is a collection of various methods and functions for processing the arrays.

Machine Epsilon in Python NumPy

Machine epsilon is suitable for double-precision numbers. We need to modify it in such a way that it also supports single precision.
An easier way to get the machine epsilon for a given float type is to use a special method provided by NumPy called numpy.finfo().

Let us understand with the help of an example,

Python code to demonstrate the example of NumPy Machine Epsilon

# Import numpy
import numpy as np

# Print the machine epsilon
print("Machine epsilon:\n",np.finfo(float).eps)

Output:
