Does "@rand(1,2)" of Windows Definition Language return 1 to 2 with same Probability ?

I want to get a random number between 1 and 2 with same probability.

 

The rand(1,2) function of Windows Definition Language seems to return 1 only, not return 2.

 

My flow for "Up and Down"

Now I use rand(1,3) instead of rand(1,2)

Does rand(1,2) return between 1 and 2 with same probability ? or need rand(1, 3) for return between 1 and 2 ?

Hi @v-monli-msft

 

My result is that rand() function return first parameter value and 2nd parameter value -1.

In result does not include 2nd parameter.

 

My test:

  @rand(1,10) result send Power BI Service streaming dataset per 1 minutes, 100 times.

  and build a report the count of each result value.

I can know rand function return value of Windows Definition Language.

and I enjoy the cooperate between Microsoft Flow to Power BI Service streaming dataset .

Hi Yoshihirok,

 

rand(1,2) should return 1 and 2. But I think rand(1,2) will only return integer right? My apologize for not quite familiar with Windows Definition Language.

Hi @v-monli-msft, Thank you for your reply

 

In document

rand: "This is used to generate a random integer within the specified range"

https://docs.microsoft.com/en-us/rest/api/logic/definition-language

 

"rand" return integer.

but, there are no-probability description.

Hi yoshihirok 

 

I am trying to use the rand function in my MS Flow to generate a random unique number id within the Assigned User ID section of the Create a Task Action. The file is read from MS forms and the task is being created as a card in MS Planner. 

 

MS Flow explains rand as rand(minValue:integer, maxValue: integer), so I have tried the following in my flow:

 

rand(1:int,10:int)

but it keeps saying invalid expression.

 

Can you please advice how I can create a random unqiue number id using an expression within Assigned User ID tab for the Create a Task Action?

 

 

Many Thanks,

 

JB

Hi yoshihirok

 

I have created a Microsoft Flow that reads a MS Forms request and then creates a task card in MS Planner. For each request that comes in I would like to give it a random unique number so it can be tracked.

 

In my create a task section, the assigned user id can have an expression provided, which is where I have tried the rand function rand(1:int,10:int) but MS Flow has said that this is not a valid expression.

 

Can you please help me to write the rand expression correctly, so I can give each created task a random unique number id?

 

Kind Regards, 

 

JB
