A Programmer Life | All Programmers Know This

"In JavaScript, you are encountering a common issue with floating-point arithmetic that can lead to unexpected results when comparing numbers. JavaScript, like many programming languages, uses a binary floating-point representation for numbers, and this representation can sometimes result in small rounding errors. When you compare 0.5 + 0.1 to 0.6, it's true because the result is exactly 0.6 with no rounding error. However, when you compare 0.2 + 0.1 to 0.3, it's false because the result is not exactly 0.3 due to a tiny rounding error in the binary representation. It's something like 0.30000000000000004, which is not equal to 0.3." - aldus ChatGPT will ai replace programmers
