## `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 ` {f:subr}`random_seed` `(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

```{literalinclude} ../../example/random/example_random_seed.f90
:language: fortran
```

## `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 = ` `dist_rand` `(n)`

### Arguments

`n`: argument has `intent(in)` is a scalar of type `integer`.

### Return value

Return a scalar of type `integer`.

### Example

```{literalinclude} ../../example/random/example_dist_rand.f90
:language: fortran
```
