Name: python-mypy-nonfloat-decimal
Version: 0.1.7
Release: 1
Summary: Mypy plugin to prevent passing float type to Decimal to avoid imprecisions.
License: MIT
URL: https://pypi.org/project/mypy-nonfloat-decimal/
Source0: https://mirrors.aliyun.com/pypi/web/packages/14/6f/4191a510d4cf4a27a67bc8776f4ee2cd005c85d4bde3890659f757017dde/mypy-nonfloat-decimal-0.1.7.tar.gz
BuildArch: noarch
Requires: python3-mypy
%description
# Mypy non-float Decimal plugin
Restricts passing float numbers to Decimal
## Why?
[The implementation of floating point numbers](https://docs.python.org/3/tutorial/floatingpoint.html)
can cause imprecisions in results. To avoid this problem you can use `Decimal` type,
however you still need to avoid passing `float` as its parameter:
```
>>> Decimal(1.02)
Decimal("1.020000000000000017763568394002504646778106689453125")
>>> Decimal("1.02")
Decimal("1.02")
```
This plugin is meant to spot occurrences where `float` is passed to `Decimal` in your code.
## Usage
- install plugin
```
pip install mypy-nonfloat-decimal
```
- add it into list of mypy plugins in your mypy config (`mypy.ini`)
```
[mypy]
plugins=mypy_nonfloat_decimal
```
- upon running mypy will detect `float` passed to `Decimal` and report it as an error (`example.py`):
```
from decimal import Decimal
Decimal(1.02)
```
```
$ mypy --config-file ./mypy.ini ./example.py
example.py:2: error: Invalid type passed to Decimal (expected "Union[int, str, Decimal]"), got float instead
```
