rand

Details #

rand(a?, b?) takes zero, one or two arguments and returns a random whole number.

• rand() gives a number from 0 up to about 2.1 billion.

• rand(limit) gives a number from 0 up to but not including limit. rand(6) is 0 to 5.

• rand(low, high) gives a number from low to high, both included. rand(1, 6) is 1 to 6.

Decimals in the arguments are cut off. For a random number with decimals, use random.

Parameters #

Takes 0 to 2 arguments. {{ rand(text?, b?) }}

Examples #

rand(1, 1)

rand(1, 6)

rand(10)

Gotchas #

• rand(0) or a negative limit stops the step: rand() needs a limit above 0.

• rand(high, low) with the first number larger stops the step: rand() needs the first number to be the smaller.

• The number is different every time the step runs, so don't use it where a repeatable result matters.
