Math helpers in $util.math
Note
We now primarily support the APPSYNC_JS runtime and its documentation. Please consider using the APPSYNC_JS runtime and its guides here.
$util.math contains methods to help with common Math operations.
-
$util.math.roundNum(Double) : Integer -
Takes a double and rounds it to the nearest integer.
-
$util.math.minVal(Double, Double) : Double -
Takes two doubles and returns the minimum value between the two doubles.
-
$util.math.maxVal(Double, Double) : Double -
Takes two doubles and returns the maximum value between the two doubles.
-
$util.math.randomDouble() : Double -
Returns a random double between 0 and 1.
Important
This function shouldn't be used for anything that needs high entropy randomness (for example, cryptography).
-
$util.math.randomWithinRange(Integer, Integer) : Integer -
Returns a random integer value within the specified range, with the first argument specifying the lower value of the range and the second argument specifying the upper value of the range.
