The below simple logic helps your requirement:

round((rand()*30),0) + 60

Thanks,

Arun

There's only one rand() function and it always returns a decimal between 0 and 1. So, you have to manipulate that number to get what you need. For example, the following would work for the scenario you described:

(rand()-0.5)/500

What if the range is decimal values like -0.001 to +0.001, cause your solution only works for integer number, any help would appreciated

Thanks Martin! I tried your method. It worked. Thank you Aloks, Chetany and Ashman. I will try your methods too.

Here's another solution:
For your case ri!upper will be 90 and ri!lower will be 60

with(

local!possibleNumbers: difference(
1+enumerate(ri!upper),
1 + enumerate(ri!lower)
),

local!count: length(local!possibleNumbers),

local!randomIndex: tointeger(local!count*(rand())),

if(local!randomIndex =0,
local!possibleNumbers[tointeger(local!count*(rand()))],

local!possibleNumbers[local!randomIndex]
)

)

Hi Brinda,
You can use following formula to achieve what you want;
= min number + tointeger(rand() * (max number - min number))
So in your case this will look like
= 60 + tointeger(rand() * (90-60))
Hope this helps!
