This class provides static helper functions for many trigonometric, logarithmic, and other mathematical operations, including methods for rounding numbers, getting absolute values, retrieving the largest whole divisor (Floor( )), and determining the remainder (IEEERemainder( )). The constants pi and e are provided as fields.
