Floating-point numbers should not be compared using == because some of these numbers cannot be exactly represented

You may expect them to be equal when comparing them, but instead they are just very close and == will come out as false

Therefore, floating-point numbers should not be compared for exact equality but instead for being close enough

The epsilon is a difference threshold for indicating that floating-point numbers are equal (it is usually 0.0001)
