/**
* @name numberToU8a
* @summary Creates a Uint8Array object from a number.
* @description
* `null`/`undefined`/`NaN` inputs returns an empty `Uint8Array` result. `number` input values return the actual bytes value converted to a `Uint8Array`. With `bitLength`, it converts the value to the equivalent size.
* @example
* <BR>
*
* ```javascript
* import { numberToU8a } from '@polkadot/util';
*
* numberToU8a(0x1234); // => [0x12, 0x34]
* ```
