# Statistical Distributions -- Pseudorandom Number Generator Module
[TOC]
## `random_seed` - set or get a value of seed to the probability distribution pseudorandom number generator
### Status
Experimental
### Description
Set or get the seed value before calling the probability distribution pseudorandom number generator for variates.
### Syntax
`call ` [[stdlib_random(module):random_seed(interface)]] `(put, get)`
### Arguments
`put`: argument has `intent(in)` and may be a scalar of type `integer`.
`get`: argument has `intent(out)` and is a scalar of type `integer`.
### Return value
Return a scalar of type `integer`.
### Example
```fortran
{!example/random/example_random_seed.f90!}
```
## `dist_rand` - Get a random integer with specified kind
### Status
Experimental
### Description
Generate an integer pseudorandom number in a specific range [-2^k, 2^k - 1] according to the input integer kind n. This pseudorandom number will be operated by bit opeartors instead of normal arithmetic operators.
### Syntax
`result = ` [[stdlib_random(module):dist_rand(interface)]] `(n)`
### Arguments
`n`: argument has `intent(in)` is a scalar of type `integer`.
### Return value
Return a scalar of type `integer`.
### Example
```fortran
{!example/random/example_dist_rand.f90!}
```
