API reference and details for NumSignalExtension from signals.dart.

NumSignalExtension#

Kind: extension | Package: package:signals_core

Extension: NumSignalExtension#

extension NumSignalExtension on ReadonlySignal<num>

Helper extensions for ReadonlySignal, providing convenient reactive math and comparison operations without needing to manually unwrap .value.

import 'package:signals_core/signals_core.dart';

final a = 5.0.$;
final sum = a + 3; // 8.0 (evaluates reactively)
final isGreater = a > 4; // true
