How do you limit the digits after a decimal in darts?

Dart Programming – truncate Method

truncateToDouble() method in my answer auto rounds decimal place based values to 1 when they are less than 1 (i.e. 0.95) which is an unwanted side effect. @alexwan02 use RegExp(r”([.]* 0+)(?!. *\d)”) to remove all trailing zeroes after the decimal point .

Dart Programming – round Method

Dart round double to N decimal places – Multiply the number by 10^N (using pow() function), then round the result to integer and divide it by 10^N . For example, we want to round double to 2 decimal places. Assume that the number is 12.3412 : Step 1: 12.3412 * 10^2 = 1234.12.16 Mar 2022

The easiest way to control rounding, and achieve a desired decimal precision, is to multiply an expression by 1, followed by the number of decimal places of precision that you want in the result . For example, multiply by 1.0000 to ensure that a result is accurate to four decimal places.

you can simply multiple the value in 100 and then round it and then divide it again into 100 . Show activity on this post. Show activity on this post. You can use toStringAsFixed in order to display the limited digits after decimal points.15 May 2016
