/**
 * @assertion 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.
 * @description Checks that returns num clamped to be in the range
 * lowerLimit-upperLimit.
