When 'x' is an integral arithmetic expression, it's now coerced to yield a signed integer before taking the absolute value of it to prevent the common issue of unsigned integer overflow/wraparound for values below zero. Using a time or interval value/expression for 'x' now also yields a time or interval, respective, from the |x| operation instead of a double.
