Name

random number

Synopsis

generate random number

generate random number

Generates a random number. By default, this is a real between 0 and 1, but you can specify a different upper bound or both bounds. If every number you specify is an integer, the result is an integer, which could be either of the bounds; otherwise it is a real. You can seed the generator to get it started; this is useful for generating a fixed pseudo-random sequence.

Example

random number
set L to {}
repeat 10 times
    if (random number 1) as boolean then
        set end of L to "heads"
    else
        set end of L to "tails"
    end if
end repeat
L -- {"heads", "tails", "heads", "heads", "heads",
     "tails", "heads", "heads", "heads", "heads"}
