craigtp / NumericHelpers.cs
Last active April 21, 2017 16:48
Provides a function that will allow two imprecise floating point numbers to be compared for "near" equality and also an "IsNumeric" function.
public static class NumericHelpers
{
// Float point maths is whack. We can't check for absolute equality as floating point numbers are imprecise
// and are subject to rounding issues (See: http://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html)
// Therefore, we can't check for absolute equality, but instead we have to need to check for values being
// "nearly" equal, which allows a small margin of error (i.e. something known as the "Epsilon" value for
// the given data type for this CPU that this code is running on).
