decimal

• Fix bad scale value by parsing 0.0 (see Issue with Decimal.tryParse return value formatting)

• loosen intl to >=0.19.0 <0.21.0 to address Intl version within flutter_localizations makes version 3.2.1 of decimal impossible to use on Flutter v3.29.3
• Bump lints to 5.0.0
• Make Decimal.zero, Decimal.one, and Decimal.ten final

• fix: toString() method for values < 0.1

• Improve performances

• Bump intl to 0.20.0, lints to 5.0.0
• Bump SDK to 3.3.0 (enables wasm)

• Fix #107: avoid exception when formatting decimal with NumberFormat.compact().

• Throw FormatException on formatter.parse('NaN').

• Add DecimalFormatter to deal with intl package. Your can now parse and format decimals.
• Add a dependency to intl.

• Introduce logical operators to DecimalIntl to support intl 0.18.0

• Update files according to license.

• Update license file to be recognized by pub.dev.

• (Breaking change) Fix Decimal.pow return type. This method now returns a Rational because 3.pow(-1) (similar to 1/3) could not be represented as a Decimal.
• Allow Rational.toDecimal() customization via its new toBigInt parameter.

• Fix toStringAsExponential returned 10.00e+7 instead of 1.00e+8

• Fix toStringAsExponential returns INFINITY by implementing toStringAsExponential without relying on double implementation.
• Fix issue to have zero.precision == 1.

• Fix toString issue with negative number between 0 and -1

The goal of this version is to have sharper types on the API and to avoid having [Decimal] objects that are not decimal numbers (1/3 for instance).

It introduces several breaking changes.

• ~/ now returns a BigInt. If you need a Decimal you can convert the BigInt to Decimal with bigint.toDecimal().
• Removal of isNaN getter. It was always returning false.
• Removal of isInfinite getter. It was always returning false.
• Removal of isNegative getter. You can replace it with decimal < Decimal.zero.
• inverse, / now return a Rational. If you need a Decimal you can convert the Rational to Decimal with rational.toDecimal(scaleOnInfinitePrecision: xxx). If you need to make several computations where inverses or divisions are involved you should make thoses operations on Rational type to avoid loosing precision and at the end convert the result back to Decimal if you want to display the result in a decimal form.

Other changes:

• round(), floor(), ceil(), truncate() now accept an optional scale to indicate at which digit the operation should be done.
• Add shift to move the decimal point.
• Add extension method hasFinitePrecision on Rational to know if a decimal form of the rational is possible without loosing precision.
• Add extension method toDecimal() on Rational.
• Add extension method toDecimal() on int.
• Add extension method toDecimal() on BigInt.

• Support json serialization as String with Decimal.fromJson/Decimal.toJson.

• Add Decimal.ten.
• Add Decimal.toBigInt.

• Add Decimal.fromBigInt.

• Add DecimalIntl to allow formatting with intl package.

• Allow negative value as exponent of pow.

• Fix typo in the description of the package.

• Stable null safety release.

• Migrate to nullsafety.

• add Decimal.pow.

• add Decimal.zero and Decimal.one.
• add Decimal.inverse.

• add Decimal.tryParse.

• migration to Dart 2.

• make Decimal.parse a factory constructor.

• allow parsing of 1.

• move to Dart SDK 2.0

• make package strong clean

• add Decimal.signum
• add Decimal.hasFinitePrecision
• add Decimal.precision
• add Decimal.scale
