evaluate method
Evaluates this expression according to given type and context.
Implementation
@override
dynamic evaluate(EvaluationType type, ContextModel context) {
if (type == EvaluationType.REAL) {
return value;
}
if (type == EvaluationType.INTERVAL) {
// interpret number as interval
final IntervalLiteral intLit = IntervalLiteral.fromSingle(this);
return intLit.evaluate(type, context);
}
if (type == EvaluationType.VECTOR) {
// interpret number as scalar
return value;
}
throw UnsupportedError('Number $this can not be interpreted as: $type');
}
