Question

What exactly is 'epsilon' in Python?

Answer 1

So, a correct definition of what epsilon means in Python might be: epsilon is the smallest positive floating point number such that (1 + epsilon) - 1 equals epsilon . That definition is wrong: machine epsilon is the number eps such that 1+eps is the next number after 1.

Answer 2

The definition of epsilon in Python is that, it is the variable that is the difference between the estimated answer and the exact answer. When the program is being repeated towards a solution, epsilon gets lesser. Hope this answer helps you.
