How can I assign the output of a function with parameters to a variable using bash?

example (){
......
local var
......
return $var 
}

user_val=$(example $number1 $number2)

I need user_val and i will it. I got error. Code can't detect the function when I try it this way.

@Barmar is correct. Replace return with echo in your function. Using var=$(...) assigns the output of the function to the variable.

When using return the value is saved in $?.
