inc()

Increments the given value by 1. If the first parameter is None or not a finite number, it resets to the third parameter. If the result exceeds the second parameter, it resets to the third parameter.

inc(value, max, reset)

• Number containing the incremented or reset value.
• None in case of an error (if 'value' is of an unsupported type).

// If 'result' is NaN or None, it becomes reset (0).
result = nan();                // returns ---
result = inc(result, 3, 0);    // returns 0
result = inc(result, 3, 0);    // returns 1
result = inc(result, 3, 0);    // returns 2
result = inc(result, 3, 0);    // returns 3
result = inc(result, 3, 0);    // returns 0
