Functions Reference

• Field3 contains 6.
Min(Field2) returns 5 when the calculation isn’t a repeating field.
Min(Field1;Field2;Field3) returns 1, 2, 7, 8 when the calculation is a repeating
field.
Note When a referenced field is a repeating field, the Min function returns the minimum
value in the first repetition field, then the minimum value in the second repetition field, and
so on.
StDev
Format
StDev(field{;field...})
Parameter
field - any related field, repeating field, or set of non-repeating fields; or an expression
that returns a field, repeating field, or set of non-repeating fields.
Parameters in curly braces { } are optional.
Data type returned
number
Description
Returns the standard deviation of the sample represented by a series of non-blank values
in:
• a repeating field (repeatingField).
• a field in matching related records
specified by (table::field), whether or not
these records appear in a portal.
• several non-repeating fields in a record
(field1;field2;field3).
• corresponding repetitions of repeating fields in a record
(repeatingField1;repeatingField2;repeatingField3), if the result is
returned in a repeating field with at least the same number of repeats.
• several fields in the first matching record specified by (table 1::field A,
table 2::field B,...). You can name a different table
for each field (table
1::field A;table 2::field B...).
Examples
A portal displays the related values 5, 6, 7, and 8 in a field called Scores.
StDev(table::Scores) returns 1.29099444....
