Question : dart round to 2 decimals
Answered by : jacob-j-van-wyk
import 'dart:math';
double roundDouble(double value, int places){ double mod = pow(10.0, places); return ((value * mod).round().toDouble() / mod);
}
main() { double num1 = roundDouble(12.3412, 2); // 12.34 double num2 = roundDouble(12.5668, 2); // 12.57 double num3 = roundDouble(-12.3412, 2); // -12.34 double num4 = roundDouble(-12.3456, 2); // -12.35
}
OR
double num1 = double.parse((12.3412).toStringAsFixed(2));
// 12.34Source : https://www.bezkoder.com/dart-round-double/ | Last Update : Tue, 21 Sep 21
