InputNumber is an input component to provide numerical input.

import { InputNumber } from 'primereact/inputnumber';

InputNumber is used as a controlled input with value and onValueChange properties.

<InputNumber value={value1} onValueChange={(e) => setValue1(e.value)} />
<InputNumber value={value2} onValueChange={(e) => setValue2(e.value)} useGrouping={false} />
<InputNumber value={value3} onValueChange={(e) => setValue3(e.value)} minFractionDigits={2} maxFractionDigits={5} />
<InputNumber value={value4} onValueChange={(e) => setValue4(e.value)} min={0} max={100} />

Localization information such as grouping and decimal symbols are defined with the locale property which defaults to the user locale.

<InputNumber value={value1} onValueChange={(e) => setValue1(e.value)} minFractionDigits={2} />
<InputNumber value={value2} onValueChange={(e) => setValue2(e.value)} locale="en-US" minFractionDigits={2} />
<InputNumber value={value3} onValueChange={(e) => setValue3(e.value)} locale="de-DE" minFractionDigits={2} />
<InputNumber value={value4} onValueChange={(e) => setValue4(e.value)} locale="en-IN" minFractionDigits={2} />

Monetary values are enabled by setting mode property as currency. In this setting, currency property also needs to be defined using ISO 4217 standard such as "USD" for the US dollar.

<InputNumber inputId="currency-us" value={value1} onValueChange={(e) => setValue1(e.value)} mode="currency" currency="USD" locale="en-US" />
<InputNumber inputId="currency-germany" value={value2} onValueChange={(e) => setValue2(e.value)} mode="currency" currency="EUR" locale="de-DE" />
<InputNumber inputId="currency-india" value={value3} onValueChange={(e) => setValue3(e.value)} mode="currency" currency="INR" currencyDisplay="code" locale="en-IN" />
<InputNumber inputId="currency-japan" value={value4} onValueChange={(e) => setValue4(e.value)} mode="currency" currency="JPY" locale="jp-JP" />

Custom texts e.g. units can be placed before or after the input section with the prefix and suffix properties.

<InputNumber value={value1} onValueChange={(e) => setValue1(e.value)} suffix=" mi" />
<InputNumber value={value2} onValueChange={(e) => setValue2(e.value)} prefix="%" />
<InputNumber value={value3} onValueChange={(e) => setValue3(e.value)} prefix="Expires in " suffix=" days" />
<InputNumber value={value4} onValueChange={(e) => setValue4(e.value)} prefix="&uarr; " suffix="℃" min={0} max={40} />

Spinner buttons are enabled using the showButtons property and layout is defined with the buttonLayout.

<InputNumber value={value1} onValueChange={(e: InputNumberValueChangeEvent) => setValue1(e.value)} showButtons mode="currency" currency="USD" />
<InputNumber value={value3} onValueChange={(e: InputNumberValueChangeEvent) => setValue3(e.value)} mode="decimal" showButtons min={0} max={100} />
<InputNumber value={value2} onValueChange={(e: InputNumberValueChangeEvent) => setValue2(e.value)} showButtons buttonLayout="horizontal" step={0.25}
            decrementButtonClassName="p-button-danger" incrementButtonClassName="p-button-success" incrementButtonIcon="pi pi-plus" decrementButtonIcon="pi pi-minus"
            mode="currency" currency="EUR" />

Buttons can also placed vertically by setting buttonLayout as vertical.

<InputNumber value={value} onValueChange={(e) => setValue(e.value)} showButtons buttonLayout="vertical" style={{ width: '4rem' }} 
    decrementButtonClassName="p-button-secondary" incrementButtonClassName="p-button-secondary" incrementButtonIcon="pi pi-plus" decrementButtonIcon="pi pi-minus" />

A floating label appears on top of the input field when focused. Visit FloatLabel documentation for more information.

    <InputNumber id="number-input" value={value} onValueChange={(e) => setValue(e.value)} />
    <label htmlFor="number-input">Number</label>

Specify the variant property as filled to display the component with a higher visual emphasis than the default outlined style.

<InputNumber variant="filled" value={value} onValueChange={(e) => setValue(e.value)} mode="decimal" minFractionDigits={2} />

Invalid state is displayed using the invalid prop to indicate a failed validation. You can use this style when integrating with form validation libraries.

<InputNumber invalid value={value} onValueChange={(e) => setValue(e.value)} mode="decimal" minFractionDigits={2} />

When disabled is present, the element cannot be edited and focused.

<InputNumber value={value} disabled prefix="%" />

Screen Reader

Value to describe the component can either be provided via label tag combined with inputId prop or using aria-labelledby, aria-label props. The input element uses spinbutton role in addition to the aria-valuemin, aria-valuemax and aria-valuenow attributes. Make sure to assign unique identifiers for the spanand input.

<label htmlFor="input-price">Price</label>
<InputNumber id="span-price" inputId="input-price" />

<span id="label_number">Number</span>
<InputNumber aria-labelledby="label_number" />

<InputNumber aria-label="Number" />
