Dart - NumberFormat

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 your help.

Answer 1

Actually, I think it's easier to go with truncateToDouble() and toStringAsFixed() and not use NumberFormat at all:

n.toStringAsFixed(n.truncateToDouble() == n ? 0 : 2); 

So for example:

main() {   double n1 = 15.00;   double n2 = 15.50;    print(format(n1));   print(format(n2)); }  String format(double n) {   return n.toStringAsFixed(n.truncateToDouble() == n ? 0 : 2); } 

Prints to console:

15 15.50
