This is a function that checks if a given character is an ASCII decimal.
Not often, as it’s relatively simple to do yourself.
This package exists because it’s needed in several related packages, at which
point it becomes useful to defer to one shared function.
This package is [ESM only][esm].
In Node.js (version 12.20+, 14.14+, or 16.0+), install with [npm][]:
``sh`
npm install is-decimal
In Deno with [Skypack][]:
`js`
import {isDecimal} from 'https://cdn.skypack.dev/is-decimal@2?dts'
In browsers with [Skypack][]:
`html`
`js
import {isDecimal} from 'is-decimal'
isDecimal('0') // => true
isDecimal('9') // => true
isDecimal('a') // => false
isDecimal('💩') // => false
`
This package exports the following identifiers: isDecimal.
There is no default export.
Check whether the given character code (number), or the character code at thestring
first position (), is decimal.
This package is fully typed with [TypeScript][].
This package is at least compatible with all maintained versions of Node.js.
As of now, that is Node.js 12.20+, 14.14+, and 16.0+.
It also works in Deno and modern browsers.
This package is safe.
