Basics
Formula: ||x|-|y||/(1 + (|x|+|y|)/2) less than eps.
Algorithm.AlmostEqual(2, 2)
// result is true
Algorithm.AlmostEqual(2.001, 2.002)
// result is false
Algorithm.AlmostEqual(2.001, 2.002, 0.01)
// result is true
GreatestCommonDivisor - This method computes the largest common divisor.
Algorithm.GreatestCommonDivisor(2, 4)
// result is 2
Hasher - This method generates hash code for a variable number of arguments. Apply
scatterer to avoid clustering. The hash scatterer will spread groups of integers that are
close through the entire range of an int.
int[ ] intArgs = new int[4]{0,3,1,6};
int hc = Algorithm.Hasher(intArgs);
Hypotenuse - This method uses Pythagoras' equation to calculate the hypotenuse. It
returns the distance along the hypotenuse.
Algorithm.Hypotenuse(1.1, 3.1)
// result is 3.28937684067971
InsideInterval - This method tests if an object is within an interval. Returns true if x
is inside the interval [low, high].
Algorithm.InsideInterval(4, 3, 5)
// result is true
Range1 intRange = new Range1(3, 5);
Algorithm.InsideInterval(3, intRange)
// result is true
Algorithm.InsideInterval(2, intRange)
// result is false
