# Input Number
Input numerical values with a customizable range.
## Basic usage
:::demo Bind a variable to `v-model` in `<el-input-number>` element and you are set.
input-number/basic
:::

## Disabled
:::demo The `disabled` attribute accepts a `boolean` , and if the value is `true` , the component is disabled. If you just need to control the value within a range, you can add `min` attribute to set the minimum value and `max` to set the maximum value. By default, the minimum value is `0` .
input-number/disabled
:::
## Steps
Allows you to define incremental steps.
:::demo Add `step` attribute to set the step.
input-number/steps
:::
## Step strictly
:::demo The `step-strictly` attribute accepts a `boolean` . if this attribute is `true` , input value can only be multiple of step.
input-number/step-strictly
:::
## Precision
:::demo Add `precision` attribute to set the precision of input value.
input-number/precision
:::
:::tip
The value of `precision` must be a non negative integer and should not be less than the decimal places of `step` .
:::
## Size
2021-12-12 17:54:21 +08:00
Use attribute `size` to set additional sizes with `large` or `small` .
