::math::prod value ?value ...?
::math::random ?value1? ?value2?
::math::sigma value value ?value ...?
::math::stats value value ?value ...?
::math::sum value ?value ...?
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::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.
