DESCRIPTION
The math package provides utility math functions. COMMANDS
::math::cov value value ?value ...? Return the coefficient of variation expressed as percent of two or more numeric values. ::math::integrate list of xy value pairs Return the area under a "curve" defined by a set of x,y pairs and the error bound as a list. ::math::fibonacci n Return the n'th Fibonacci number. ::math::max value ?value ...? Return the maximum of one or more numeric values. ::math::mean value ?value ...? Return the mean, or "average" of one or more numeric values. ::math::min value ?value ...? Return the minimum of one or more numeric values. ::math::prod value ?value ...? Return the product of one or more numeric values. ::math::random ?value1? ?value2? Return a random number. If no arguments are given, the number is a floating point value between 0 and 1. If one argument is given, the number is an integer value between 0 and value1. If two arguments are given, the number is an integer value between value1 and value2. ::math::sigma value value ?value ...? Return the population standard deviation of two or more numeric values. ::math::stats value value ?value ...? Return the mean, standard deviation, and coefficient of variation as percent as a list. ::math::sum value ?value ...? Return the sum of one or more numeric values. KEYWORDS
