rand() function not doing whats written in its description

[JaFeKl]

Hello everyone,

I'm trying to generate a random number between 0 and 2.

The rand()-functions descriptions says something like:   "... (including both corner numbers)" 

The below screenshot is in german, but I assume the english meaning is clear.

However, after some test, rand(0,2) definitly generates only either 0 or 1, not including the upper border 2.

Can anyone verify this behavior?

Hi @JaFeKl,

Thanks for your feedback!

Please refer to the document:

https://docs.microsoft.com/en-us/azure/logic-apps/workflow-definition-language-functions-reference#r...

This example gets a random integer from the specified range, excluding the maximum value:

rand(0,2) it will return 0 or 1. If you want to return 0,1 or 2, it should be rand(0,3).

Then you should definitely change the functions description in flow which is misleading, since it says that the upper max value is included.
