MIN( ) Function
Evaluates a set of expressions and returns the expression with the minimum value.
MIN(eExpression1, eExpression2 [, eExpression3 ...])
Return Value
Character, Numeric, Currency, Double, Float, Date, or DateTime
Parameters
- eExpression1, eExpression2[, eExpression3...]
Specify the set of expressions from which you want MIN( ) to return the expression with the lowest value. All the expressions must be of the same type.
Example
The following example uses APPEND BLANK to create a table with 10 records containing random values, then uses MIN( ) and MAX( ) to display the maximum and minimum values in the table.
CLOSE DATABASES
CREATE TABLE Random (cValue N(3))
FOR nItem = 1 TO 10 && Append 10 records,
APPEND BLANK
REPLACE cValue WITH 1 + 100 * RAND( ) && Insert random values
ENDFOR
CLEAR
LIST && Display the values
gnMaximum = 1 && Initialize minimum value
gnMinimum = 100 && Initialize maximum value
SCAN
gnMinimum = MIN(gnMinimum, cValue)
gnMaximum = MAX(gnMaximum, cValue)
ENDSCAN
? 'The minimum value is: ', gnMinimum && Display minimum value
? 'The maximum value is: ', gnMaximum && Display maximum value
