# Seeding And Generating Random Integers
|
|
|
|
It is easy enough to generate a series of random numbers using the `Random`
|
|
module's `int` function.
|
|
|
|
```reason
|
|
Random.int(10);
|
|
```
|
|
|
|
This will generate a random integer between 0 and 9.
|
|
|
|
You may notice that the randomness is the same each time you run your
|
|
program. That is because you have fixed seed. To make sure you have a
|
|
different seed each time your program runs, you can initialize the random
|
|
number generator with something different at each run, such as the current
|
|
time.
|
|
|
|
```reason
|
|
Random.init(int_of_float(Js.Date.now()));
|
|
```
