Description
Returns the median of all values in parenthesis. Range
can be a set of constants or input variable separated by
commas, or a range of inputs designated by a colon
between the two ends of the range (e.g. AI1:AI7).
Returns the sum-square of all values in parenthesis.
Each input or constant is squared, and then added
together. Range can be a set of constants or input vari-
able separated by commas, or a range of inputs desig-
nated by a colon between the two ends of the range
(e.g. AI1:AI7).
Returns the product of all values in the range multi-
plied together. Range can be a set of constants or input
variable separated by commas, or a range of inputs
designated by a colon between the two ends of the
range (e.g. AI1:AI7).
Returns the maximum value of all values in the range.
Range can be a set of constants or input variable sepa-
rated by commas, or a range of inputs designated by a
colon between the two ends of the range (e.g.
AI1:AI7).
Returns the minimum value of all values in the range.
Range can be a set of constants or input variable sepa-
rated by commas, or a range of inputs designated by a
colon between the two ends of the range (e.g.
AI1:AI7).
Returns the average value of all values in the range.
Range can be a set of constants or input variable sepa-
rated by commas, or a range of inputs designated by a
colon between the two ends of the range (e.g.
AI1:AI7).
Returns the sum of all values in the range. Range can
be a set of constants or input variable separated by
commas, or a range of inputs designated by a colon
between the two ends of the range (e.g. AI1:AI7).
Returns a random number between low and high every
time the algorithm is updated (every few seconds).
