[ range ]
The [range] method tests a value to see if it exists within a given range. The method takes three parameters, the value to be tested and the minimum and maximum values of the test range. [range] will always return one of the three parameters it receives.
range(val, min, max) returns:
- val when min < val < max
- min when val < min
- max when val > max

To ensure that values lie within a specified range
Use the [range] method. This example normalises a set of data to fit within the specified range.
Code
var( myValues = array(22, 30, 17, 5, 16, 25, 21, 24),
constrainedValues = array )
with v in $myValues
do => {
$constrainedValues->insert( range( #v, 16, 24 ) )
}
$constrainedValuesResult
array(22, 24, 17, 16, 16, 24, 21, 24)
