eslint-plugin-no-arithmetic

ESLint plugin containing a rule for detecting arithmetic in JavaScript source. Floating-point math can lead to imprecise results, so this plugin directs users to float-safe alternative helper methods.

Configuration

Add the following to your eslint config:

``js
{
//...
plugins: [
// ...
"@vertical-made/no-arithmetic",
// ...
],
rules: {
"@vertical-made/no-arithmetic/no-arithmetic": "error",
// ...
}
}
`

Or with a custom alternative suggestion:

`js
{
//...
plugins: [
// ...
"@vertical-made/no-arithmetic",
// ...
],
rules: {
"@vertical-made/no-arithmetic/no-arithmetic": [
"error",
{ message: "use the floatSafe* helpers in myUtils.js" }
// ...
}
}
`

Options

$3

Sets the hint message.

> type: string
>
> default: "use float-safe alternatives"

$3

When enabled, does _not_ error on operations that look like an increment / decrement. We define this as the right-hand value of a binary + / - operation being the literal value 1.

> type: boolean
>
> default: true`
