Dart / Flutter-如何在格式化值时如何避免通过NumberFormat.compactCurrency(locale:“en_IN”)。format()方法完成的自动舍入？

num value = 29886964;
NumberFormat numberFormat = NumberFormat.compactCurrency(locale: "en_IN");
String output = numberFormat.format(value);

实际产量= INR2.99Cr
需求/期望:INR2.98Cr

Answer 1

使用NumberFormat.currency API

num value = 29886964;
NumberFormat numberFormat = NumberFormat.compactCurrency(locale: "en_IN" );
final count = math.pow(10 , (value.toString().length - numberFormat.significantDigits));
var result = value / count;
String output = numberFormat.format(result.floor() * count);
print(output);

值:INR2.98Cr
