   How to compare two floating-point numbers for almost-equality in Python?

   • Output: Comparing floating-point numbers for almost-equality requires careful handling due to precision limitations. By using methods such as absolute tolerance, relative tolerance, and Python’s built-in math.isclose () function, we can accurately determine if two floating-point numbers are nearly equal.

   Does 0 equal a not-zero?

   • No matter how many digits you are looking at, 0 will not equal a not-zero. This could prove to be a headache for such tests if you have a case whose correct answer is zero. There are lots of ways of comparing two numbers to see if they agree to N significant digits.
