# Key Points:
# Floating-Point Representation:

# Numbers like 0.1, 0.2, and 0.3 cannot be represented exactly in binary. Instead, they are stored as approximations, which leads to rounding errors.
# These errors occur because some decimal fractions cannot be represented as finite binary fractions (similar to how 1/3 in decimal is a repeating fraction: 0.333...).
# Languages with Similar Behavior: The issue of 0.1 + 0.2 != 0.3 happens in most programming languages, including but not limited to:

# C
# C++
# Java
# JavaScript
# C#
# Ruby
# Go
# PHP
# Swift
