`RANDOM_NUMBER`

— Pseudo-random number*Description*:- Returns a single pseudorandom number or an array of pseudorandom numbers
from the uniform distribution over the range 0 \leq x < 1.
The runtime-library implements the xorshift1024* random number generator (RNG). This generator has a period of 2^1024 - 1, and when using multiple threads up to 2^512 threads can each generate 2^512 random numbers before any aliasing occurs.

Note that in a multi-threaded program (e.g. using OpenMP directives), each thread will have its own random number state. For details of the seeding procedure, see the documentation for the

`RANDOM_SEED`

intrinsic. *Standard*:- Fortran 95 and later
*Class*:- Subroutine
*Syntax*:`RANDOM_NUMBER(HARVEST)`

*Arguments*:-
`HARVEST`Shall be a scalar or an array of type `REAL`

. *Example*:-
program test_random_number REAL :: r(5,5) CALL RANDOM_NUMBER(r) end program
