|
|
|
|
Reactive numeric projection from one domain to another.

|
|
|
## Usage
|
|
|
|
```ts
|
|
import { useProjection } from '@vueuse/math'
|
|
|
|
const input = ref(0)
|
|
const projected = useProjection(input, [0, 10], [0, 100])
|
|
|
|
input.value = 5 // projected.value === 50
|
|
input.value = 10 // projected.value === 100
|
|
```
|
|
|
|
## Type Declarations
