Mathematical functions

This page describes the additional set of predefined Jsonnet functions for the Data Transformer Script task available in Application Integration.

Before you begin

To use the following predefined functions, you must import the functions library in your script. Importing the functions library lets you use both the standard Jsonnet functions and the predefined Data Transformer functions.

Application Integration supports Jsonnet functions library v0.20.0. For information about the Jsonnet standard functions, see Jsonnet Standard Library.

`Is Decimal`

Syntax	isDecimal(num)
Description	Checks if the given number is a decimal.
Input parameter	num: The input number.
Return type	`BOOLEAN`
Output	Returns TRUE if the number is a decimal and FALSE otherwise.

`Is Even`

Syntax	isEven(num)
Description	Checks if the given number is even.
Input parameter	num: The input number.
Return type	`BOOLEAN`
Output	Returns TRUE if the number is even and FALSE otherwise.

`Is Integer`

Syntax	isInteger(num)
Description	Checks if the given number is an integer.
Input parameter	num: The input number.
Return type	`BOOLEAN`
Output	Returns TRUE if the number is an integer and FALSE otherwise.

`Is Odd`

Syntax	isOdd(num)
Description	Checks if the given number is odd.
Input parameter	num: The input number.
Return type	`BOOLEAN`
Output	Returns TRUE if the number is odd and FALSE otherwise.

`Random Number`

Syntax	randomNumber(lowerBound, upperBound)
Description	Generates a random real number between a specified range.
Input parameter	lowerBound: Lower range value (inclusive). Default value is `0`. upperBound: Higher range value (exclusive). Default value is `1`.
Return type	A real number.
Output	Returns a random real number between `lowerBound` and `upperBound`.

`Round`

Syntax	round(input)
Description	Rounds off a number to the nearest integer.
Input parameter	input: A value to round off.
Return type	`INTEGER`
Return value	Returns the nearest rounded off integer.
