# RANF Portability Routine

Portability Function: Generates a random number between 0.0 and RAND_MAX. RANF can be used as a portability routine or as an intrinsic procedure. It is an intrinsic procedure unless you specify USE IFPORT.

## Module

USE IFPORT

result = RANF ( )

## Results

The result type is REAL(4). The result value is a single-precision pseudo-random number between 0.0 and (2**31) - 1.

The initial seed is set by the following:

      CALL SRAND(ISEED)

where ISEED is type INTEGER(4).
