Returns the smaller of two numeric values.
MIN function consumes two numeric parameters from the top of the stack and pushes back the smallest value.
Since 2.6.0, this function can be applied to a LIST of numerical values and a numerical value. The order of the parameter is very important in that case: considering this function as
F, the result of
[ $a $b $c ] F is
$a $b F $c F ] but the result of
[ $a $b ] $c F is
[ $a $c F $b $c F ].
Since 2.7.1, this function can be applied to a GTS of numerical values. This is very similar to how this function works on LISTs, considering the values of the GTS. In that case, the order of the parameters also matters and the result is either a GTS or a single numerical value.
