Question

Is there a way with NumberFormat to display :

• \'15\' if double value is 15.00
• \'15.50\' if double value is 15.50

Thanks for yo

Answer 1

A variant of double value formatting:

void main (){
  final n1 = 15.00;
  final n2 = 15.50;
  print(format(n1));
  print(format(n2));
}
String format(double n) {
  final fraction = n - n.toInt();
  if (fraction == 0.0) {
    return n.toString();
  }
  var twoDigitFraction = (fraction * 100).truncateToDouble().toInt();
  return '${n.toInt()}.$twoDigitFraction';
}
