clamp abstract method
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);
