Random Number

Overview​

This section describes Bizagi random number functions. These functions are as follows:

  • Rand(from, to)
  • Rand()

Rand (from, to)​

This function returns an integer random number between two numbers.

CHelper.Math.Rand(ValueFrom, ValueTo)

The parameters of this function can be defined as Xpaths, variables, or numbers.

Considerations​

  • Input parameters must be integers.
  • The supported attribute type to use as input XPath parameter (or Xpaths stored in variables) is integer.
  • The function returns an error if the ValueFrom is greater than the ValueTo parameter.
  • Use the IsNaN function to validate the parameters used are numbers.

Example​

A company uses Bizagi to raffle different prizes among its clients. Each customer is given a number between 0 and 100. Bizagi must generate a random number between the available numbers to obtain a winner.

To implement this logic you can use the Rand function:

Math10

//Generate the winner number

<RaffleProcess.WinnerNumber> = CHelper.Math.Rand(0,100);

Rand()​

This function returns a decimal between 0.0 and 1.0, and it has NO parameters.

CHelper.Math.Rand()

Example​

Suppose you need to generate a random number between 10 and 20 with two decimal places.

You have to use two functions: one to generate a random number between 10 and 20 and one to generate the decimal places. Then you can add both results.

Math25

<Request.RandomNumber> = (CHelper.Math.Rand(10,20))+(CHelper.Math.Rand());
