asFixed method

String asFixed(int precision, { bool removeTrailingZeros = true, })

Implementation

String asFixed(int precision, {bool removeTrailingZeros = true}) {
  // precision is the number of decimal places after the decimal point to keep
  int offset = _decimal + precision - 1;
  int extraZeroes = precision - (_digits.length - offset);
  if (extraZeroes > 0) {
    _digits.addAll(
        Formatter.getPadding(extraZeroes, '0').split('').map(int.parse));
  }
  _round(offset + 1, offset);
  String ret = _digits.sublist(0, _decimal).fold('', (i, e) => "$i$e");
  List<int> trailingDigits = _digits.sublist(_decimal, _decimal + precision);
  if (removeTrailingZeros) {
    trailingDigits = _removeTrailingZeros(trailingDigits);
  }
  var trailingZeroes = trailingDigits.fold('', (i, e) => "$i$e");
  if (trailingZeroes.length == 0) {
    return ret;
  }
  ret = "$ret.$trailingZeroes";
  return ret;
}
