# Input Number

```rust demo
let value = create_rw_signal(0);
let value_f64 = create_rw_signal(0.0);

view! {
    <Space vertical=true>
        <InputNumber value step=1/>
        <InputNumber value=value_f64 step=1.0/>
    </Space>
}
```

### Disabled

```rust demo
let value = create_rw_signal(0);

view! {
    <InputNumber value step=1 disabled=true/>
}
```

### Invalid

```rust demo
let value = create_rw_signal(0);

view! {
    <InputNumber value step=1 invalid=true/>
}
```
