# Overview

The Fixed package allows you to store and perform math on decimal numbers with a fixed scale (fixed no. of decimal places).

All amounts are stored as BigInts to allow precision math to be performed.

## Sponsored by OnePub

### Features

The features of Fixed are:

* Fixed uses a selectable fixed scale (no. of decimal places)
* Fixed provides a builtin formatter and parser `Fixed.format(pattern)`
* Fixed includes a convenience method `Fixed.formatIntl(locale)` which formats the number with the provided locale or the default locale if not provided.
* You can create a Fixed instance from a number sources

```dart
var t1 = Fixed.fromNum(1); /// == 1.00
var t2 = Fixed.fromNum(1, scale: 3); /// == 1.000

var add = t1 + 10;
var multiply = t1 * t2;

var t3 = Fixed.parse("1.23356"); // == 1.23356, scale: 5

if (t1 == t2) // true
{
    print(t1.format('0.##')); // '1.00'
}

```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://fixed.onepub.dev/overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
