Definition
INT rand ( <INT lowerlimit> , <INT upperlimit> )
Returns a random number, ranging from a certain lower limit to a certain upper limit. The limits are within the range.
Make sure the difference between lowerlimit and upperlimit does not exceed 32767 (2^15).
Parameters
| INT lowerlimit | - The lower limit for the random value. |
| INT upperlimit | - The upper limit for the random value. |
Returns
INT : A random value: lowerlimit <= result <= upperlimit
