A random number generator.

Notes

  • Port inputs default to 0 and 1 respectively.
  • The Min input is included while the Max input is excluded, meaning: if the min and max inputs are 0 and 5 respectively, it may generate a number within 0 to 5, possibly 0, but never 5.
  • The random block will generate a new value every time it is executed. To reuse the same random value, it should be stored in a variable.
  • Note that the output would be in decimal. To avoid this use a rounding operation, ideally floor and secondarily round. Ceiling also works but is scarcely used.
  • The random block behaves inconsistently when used with wire splits:

Examples

Either generate -1 or 1.

Output a random integer with equal probability.
