Examples

# Example 1


  puts rand
  rand_skip
           
  puts rand

# Basic rand stream skip
# prints 0.75006103515625
# jump random stream forward one
# typically the next rand is 0.733917236328125
# prints 0.464202880859375

# Example 2


  puts rand
  puts rand
  puts rand
  puts rand
  rand_reset 
  puts rand
  rand_skip(2)
              
              
              
  puts rand 0.24249267578125

# Jumping forward multiple places in the rand stream
# prints 0.75006103515625
# prints 0.733917236328125
# prints 0.464202880859375
# prints 0.24249267578125
# reset the random stream
# prints 0.75006103515625
# jump random stream forward three places
# the result of the next call to rand will be
# exactly the same as if rand had been called
# three times
