## rollSubWithLower() Function

Generates random numbers to emulate dice rolls. The

`sub`

parameter is subtracted from each die and all intermediate results that are then lower than the `minimum`

parameter are replaced with that value instead. The total is returned.### Usage

`rollSubWithLower(times, sides, sub, minimum)`

**Parameters**

`times`

- The number of times to roll the dice.`sides`

- The number of sides the dice possess.`sub`

- The number to subtract from each die roll.`minimum`

- The minimum value (after the subtraction) that each individual die will contribute to the total.

### Examples

Roll five twenty-sided dice. Subtract 2 from each. Any value now lower than 3 is treated as 3.
Returns a number that is between 15 and 90 (and no longer 5 to 100 as with a regular

`[t: rollSubWithLower(5, 20, 2, 3)]`

`5d20`

roll).### See Also
