RANDOM

Summary

RANDOM returns a random value for the provided datatype

Category

MATH

Usage

RANDOM value

Arguments

value - can be of types BYTE! (like up to 255) or INTEGER! type

Refinements

/PSEUDO - will give you a deterministic sequence for which RANDOM/SEED will work

/SECURE - gives a true random value for which RANDOM/SEED is not needed

/SEED - randomizes the function

Description

RANDOM returns a random value for the provided datatype

Example Code

The next example returns a random BYTE! value

RANDOM/SEED NOW ; Uses current time to randomize data
value: RANDOM 100

Note that it does not limit the returned value to the given value, but it returns a random BYTE! value so 1 up to 255. Not all these functionalities are available on all platforms, so RANDOM gives you a platform default, usually RANDOM/PSEUDO .

Example RANDOM/PSEUDO

repeat 80 [
  h: random/pseudo 255
  write h write " "
]
write/line ""
repeat 80 [
  h: random/pseudo 255
  write h write " "
]

This returns different data on the two lines, but when you run again, the generated numbers are the same as last time.

RANDOM/SECURE is currently only implemented for Unix platforms
