DESCRIPTION
The math package provides utility math functions.
COMMANDS
::math::cov value 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 num
ber. ::math::max value ?value? ?value ...? Return
the maximum of one or more numeric values.
Return the mean, or "average" of one or more
numeric values.
::math::min value ?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 argu
ments are given, the number is an integer value
between value1 and value2.
::math::sigma value value ?value? ?value ...?
Return the population standard deviation of two or
more numeric values.
::math::stats value value ?value? ?value ...?
Return the mean, standard deviation, and coeffi
cient of variation as percent as a list.
::math::sum value ?value ...?
Return the sum of one or more numeric values.
