round real values to the n-th decimal?

I believe the "round" function available in generate attributes will do what you want quite easily!  

You also have the 'format numbers' operator but that will turn it into a nominal value.

How do I insert the round in the function expression? 

Tried using 

Function expression

rand(round())

also two separate function expressions no luck 

attribute 1 rand()

attribute 1 round()

also if maybe you know, how do I limit the random function between two numbers rand(1,5) does not work at all. 

Thank you in advance. 

Hi @SHSguy,

I am not sure what you want to achieve in your first use case.

If you want to round a random number the order of functions is wrong. It needs to be round(rand(),x) with x being the number of decimals to round to.

Regarding your second question:

The rand() function always delivers a floating point number between 0 and 1. So one possible solution would be

rand()*5

 to get values between 0 and 5. If want them rounded to the next integer you would do

ceil(rand()*5)

ceil() rounds to the next integer "above"

floow() rounds to the next integer "below"

P.S.:

An explanation to all function is given if you click on the i next to the function (see screenshot)

Hi Edin, 

Thank you really appreciate the explanation.
