clamp abstract method

num clamp(num lowerLimit, num upperLimit)

Returns this num clamped to be in the range lowerLimit-upperLimit.

The comparison is done using compareTo and therefore takes -0.0 into account. This also implies that double.NAN is treated as the maximal double value.

The arguments lowerLimit and upperLimit must form a valid range where lowerLimit.compareTo(upperLimit) <= 0.
