The `min` and `max` props can be used to define a range of accepted values. You can pass only one of them to define an open-ended range.

```tsx
<NumberInput min={-10} max={10} />
<NumberInput min={-10} max={10} />

// Open-ended
<NumberInput min={0} />
// Open-ended
<NumberInput min={0} />
```

The `step` prop can be used to defined the granularity of the change in value when incrementing or decrementing. For example, if `min={0}` and `step={2}`, valid values for the component would be 0, 2, 4… since the value can only be changed in increments of 2.

:::warning
Support for decimal values or step sizes isn't available yet, but you can upvote [this GitHub issue](https://github.com/mui/material-ui/issues/38518) to see it arrive sooner!
:::

When the input field is in focus, you can enter values that fall outside the valid range. The value will be clamped based on `min`, `max` and `step` once the input field is blurred.

Holding down the <kbd>Shift</kbd> key when interacting with the stepper buttons applies a multipler (default 10x) to the value change of each step.
