Random numbers

random()

Retrieves the next random value, restricted to a given range.

random(max);

Parameters

• max - the upper limit of the random number to retrieve.

Returns: a random value between 0 and up to, but not including max.

int r = random(10);
// r is >= 0 and < 10
// The smallest value returned is 0
// The largest value returned is 9

NB: When max is 0, the result is always 0.

random(min,max);

Parameters:

• min - the lower limit (inclusive) of the random number to retrieve.
• max - the upper limit (exclusive) of the random number to retrieve.

Returns: a random value from min and up to, but not including max.

int r = random(10, 100);
// r is >= 10 and < 100
// The smallest value returned is 10
// The largest value returned is 99

NB: If min is greater or equal to max, the result is always 0.
