### 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
