remove decimal in dart

I have a number: 466.62 as a double and can't change it to a string, how can I get rid of the decimal point and print 46662? I've managed to get 46662.0 by multiplying the value by 100, but I don't want to print the decimal point. Thanks

To remove decimals from use effective integer division

int x =  (12345679.900 ~/ 1000)

~/ is effective integer operator and removes decimals .

You can do integer division by 1 and then turn it into a string

final String number = ((466.62 * 100) ~/ 1).toString();

Or just truncate

final String number = (466.62 * 100).truncate().toString();

More on the ~/ operator https://api.flutter.dev/flutter/dart-core/num/operator_truncate_divide.html

After you have managed to get this 46662.0,

Use this :

46662.0.toStringAsFixed(0);

print(46662.0.toStringAsFixed(0)); - This gives 46662

print(46662.0.toStringAsFixed(0).runtimeType); - This gives as String.

When you multiply 466.62 by 100, your end result will remain a double as well. This is why you are seeing 46662.0. So you need to convert it to Int value, so instead you should do it like this:

double vDouble = 466.62 *100
String vString = vDouble.toInt().toString();

This will give you 4662.

For a more generic case, use the String split method; 

String str = '466.62';

//split string
var arr = str.split('.');

print(arr[0]); //will print 466
print(are[1]); //will print 62
