clamp method

num clamp(

1. num lowerLimit,
2. 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.

Example:

var result = 10.5.clamp(5, 10.0); // 10.0
result = 0.75.clamp(5, 10.0); // 5
result = (-10).clamp(-5, 5.0); // -5
result = (-0.0).clamp(-5, 5.0); // -0.0

Implementation

num clamp(num lowerLimit, num upperLimit);
