Description

The RANDOM_NUMBER subroutine returns a uniformly distributed pseudorandom number or numbers in the range 0 ≤ x < 1 .

    
Syntax
 
RANDOM_NUMBER (harvest)
 

Arguments

harvest is an INTENT(OUT) scalar or array of type REAL. On return, its value is a set of pseudorandom numbers uniformly distributed in the range 0 ≤ x < 1 .

Remarks

The random number generator uses a multiplicative congruential algorithm with a period of approximately 2³⁸

    
Example
 
       call random_number(x) ! each element of x is assigned
                             ! a pseudorandom number
