Props

| Name | Type | Default | Description |
| -------------------------------------------------- | ---------- | -------------- | ---------------------------------------------------------------------------------------------- |
| allowDecimals | boolean | true | Allow decimals |
| allowNegativeValue | boolean | true | Allow user to enter negative value |
| defaultValue | number | | Default value |
| value | number | | Programmatically set the value |
| onValueChange | function | | Handle change in value |
| placeholder | string | | Placeholder if no value |
| decimalsLimit | number | 2 | Limit length of decimals allowed |
| decimalScale | number | | Specify decimal scale for padding/trimming eg. 1.5 -> 1.50 or 1.234 -> 1.23 if decimal scale 2 |
| fixedDecimalLength | number | | Value will always have the specified length of decimals |
| prefix | string | | Include a prefix eg. £ or \$ |
| suffix | string | | Include a suffix eg. € or % |
| decimalSeparator | string | locale default | Separator between integer part and fractional part of value |
| groupSeparator | string | locale default | Separator between thousand, million and billion |
| intlConfig | object | | International locale config |
| disabled | boolean | false | Disabled |
| disableAbbreviations | boolean | false | Disable abbreviations eg. 1k -> 1,000, 2m -> 2,000,000 |
| disableGroupSeparators | boolean | false | Disable auto adding the group separator between values, eg. 1000 -> 1,000 |
| maxLength | number | | Maximum characters the user can enter |
| step | number | | Incremental value change on arrow down and arrow up key press |
| transformRawValue | function | | Transform the raw value from the input before parsing. Needs to return string. |

$3

It can parse values with abbreviations k, m and b

Examples:

- 1k = 1,000
- 2.5m = 2,500,000
- 3.456B = 3,456,000,000

This can be turned off by passing in disableAbbreviations.

$3

You can add a prefix or suffix by passing in prefix or suffix.

`js
import CurrencyInput from 'solid-currency-input-field'
;
// £123
;
// 456%
`

Note: Passing in prefix/suffix will override the intl locale config.

$3

You can change the decimal and group separators by passing in decimalSeparator and groupSeparator.

Example:

`js
import CurrencyInput from 'solid-currency-input-field'
;
`

Note: the separators cannot be a number, and decimalSeparator must be different to groupSeparator.

To turn off auto adding the group separator, add disableGroupSeparators={true}.

$3

This component can also accept international locale config to format the currency to locale setting.

Examples:

`javascript
import CurrencyInput from 'react-currency-input-field'
;
;
;
`

locale should be a BCP 47 language tag, such as "en-US" or "en-IN".

currency should be a ISO 4217 currency code, such as "USD" for the US dollar, "EUR" for the euro, or "CNY" for the Chinese RMB.

Any prefix, suffix, group separator and decimal separator options passed in will override the default locale settings.

$3

decimalsLimit and decimalScale sound similar but have different usages.

decimalsLimit prevents the user from typing more than the limit, and decimalScale will format the decimals onBlur to the specified length, padding or trimming as necessary.

Example:

`md
If decimalScale is 2

- 1.5 becomes 1.50 (padded)
- 1.234 becomes 1.23 (trimmed)

---

If decimalLimit is 2

- User enters 1.23
- User is then prevented from entering another value
`

$3

Use fixedDecimalLength so that the value will always have the specified length of decimals.

This formatting happens onBlur.

Example if fixedDecimalLength was 2:

`md
- 1 -> 1.00 -> 1.23
- 12.3 -> 12.30
- 12.34 -> 12.34
`

Format values for display

Use the formatValue function to format the values to a more user friendly string. This is useful if you are displaying the value somewhere else ie. the total of multiple inputs.

`javascript
import { formatValue } from 'solid-currency-input-field'

// Format using prefix, groupSeparator and decimalSeparator
const formattedValue1 = formatValue({
value: '123456',
groupSeparator: ',',
decimalSeparator: '.',
prefix: '$',
})

console.log(formattedValue1)
// $123,456

// Format using intl locale config
const formattedValue2 = formatValue({
value: '500000',
intlConfig: { locale: 'en-IN', currency: 'INR' },
})

console.log(formattedValue2)
// ₹5,00,000
