Remarks

Two apparently equivalent floating-point numbers may not compare equal because of differences in their least significant digits. This is usually caused by round-off error resulting from the finite precision of floating-point representations. For example, the C# expression, (double)1/3 == (double)0.33333, does not compare equal because the division operation on the left-hand side has maximum precision while the constant on the right-hand side is only precise to the visible digits.

Instead, determine if the two sides of a comparison are close enough to equal for your purposes. The DoubleComparer class lets you specify the tolerance within which two numbers are considered equal.
