Generating random numbers is a common requirement for many problems. The following provides a summary of utilizing the built-in Fortran random number generator routines.
- 23.1: Initialization
- The first step in generating random numbers is to initialize the Fortran random number generator, random_seed().
- 23.2: Generating Random Number
- To request a random number, a real variable must be declared and then passed to the following call to the built-in random_number() routine.
- 23.3: Example
- A simple example program to generate 100 random integer numbers, each between 1 and 100.
- 23.4: Example
- In order to generate different random number for successive executions, the seed must be initialized with a different set of seed values each time.
