Hi Guys, Welcome to Proto Coders Point. This article is all about how to round number to decimal places in flutter/dart.
What do mean by round to decimal places
Check out below image
Flutter round number to decimal places will make use of a in-build method, .toStringAsFixed(2) will help us in getting how much fraction Digits we need after the decimal point and the last number will get round up.
Example
var num = 15.12345; print(num.toStringAsFixed(3)); ///
Here in .toStringAsFixed(3), Here 3 defines the parameter, How many decimal number you want after decimal point.
Example:
void main(){
var n = 15.12345;
print(n.toStringAsFixed(3)); // 15.123
var x = 4.56;
print(x.toStringAsFixed(1)); // 4.6
var x1 = 4.53;
print(x1.toStringAsFixed(1)); // 4.5
var y = -1.55;
print(y.toStringAsFixed(1)); // -1.6
var z = 10.5677;
print(z.toStringAsFixed(3)); // 10.568
var num = 10.85;
print(z.toStringAsFixed(0)); // 10
}
why does flutter uses dart language
dart decimal grouping, add commas to number
convert set to list, list to sets in dart
