Random Numbers
random($min, $max)
Returns a random number between $min and $max (inclusive), with step size 1.
Sample usage:
$x = random(5, 10); # assigns $x to be a random number between 5 and 10 inclusive, with step size 1.
random($min, $max, $step)
Returns a random number between $min and $max (inclusive), with step size $step.
Sample usage:
$x = random(5, 10, .25); # assigns $x to be a random number between 5 and 10 inclusive, with step size .25
rands($min, $max, $n)
Returns $n values from $min to $max with a step size of 1
Sample usage:
@randvals = rands(2, 10, 4); # @randvals will contain 4 random values from 2 to 10
rrands($min, $max, $step, $n)
Returns $n values from $min to $max with a step size of $step
Sample usage:
@randvals = rrands(2, 10, .25, 4); # @randvals will contain 4 random values from 2 to 10 with a step size of .25
diffrands($min, $max, $n)
Returns $n different values from $min to $max with a step size of 1
Sample usage:
@randvals = diffrrands(2, 10, 4); # @randvals will contain 4 different random values from 2 to 10
diffrrands($min, $max, $step, $n)
Returns $n different values from $min to $max with a step size of $step
Sample usage:
@randvals = diffrrands(2, 10, .25, 4); # @randvals will contain 4 different random values from 2 to 10 with a step size of .25
Random elements of lists
randfrom(@list)
Returns a randomly selected element from @list
Sample usage:
@list = (3, 5, 7, 9);
$element = randfrom(@list) # $element will be a randomly selected element from @list
randsfrom(@list, $n)
Returns $n different values from @list
Sample usage:
@list = (3, 5, 7, 9);
@sublist = randsfrom(@list, 2) # @sublist will contain two different, randomly selected elements from @list
