🔍 Detect Floating Point Precision Loss

❓ Problem Statement

In C++, floating-point numbers (e.g., float, double) can lead to precision errors when performing arithmetic operations.

You are given two floating-point numbers a and b, and an expected result expected_sum.
Write a C++ program that checks if the sum of a + b is "almost equal" to expected_sum within a small epsilon tolerance (1e-6).

Return "YES" if it matches, "NO" otherwise.
