Publisher review:Numerical performs several types of numerical and statistical functions. This class performs several types of numerical and statistical functions. Features:
-generates gaussian normal distributions, -does numerical integration of arbitrary functions, -generates random numbers with gaussian distributions, -provides a number of standard statistical functions, e.g., mean, standard deviation, variance, etc., -has two different methods of solving for the roots of an equation (bisection and steepest descent), -converts floating point to rational number representation (useful for infinite precision calculations), -generates a Sieve of Erastophenes for a specified integer, -factors integers into their prime factors.
