Compares two numbers to see if they are within epsilon of each other
namespace HH\Lib\Math; function almost_equals( num $num_one, num $num_two, num $epsilon = 1.0E-8, ): bool;
If the difference equals epsilon this returns false.
default epsilon of .00000001.
When comparing large numbers consider passing in a large epsilon
num $epsilon = 1.0E-8
