Mathematical Functions

Procedures that work with numbers mathematically.

Description
   This set of procedures provide basic algebraic and trigonometric 
   function. Random numbers can also be retrieved, using a variety of 
   random number generators.

Algebraic Procedures
   Absolute values, logarithms, square roots and more.
Trigonometry Procedures
   Sine, Cosine and other trigonometry-related procedures.
Miscellaneous Procedures
