|
| 5 | * @summary Creates a hex value from a BN.js bignumber object.
|
| 6 | * @description
|
| 7 | * `null` inputs returns a `0x` result, BN values return the actual value as a `0x` prefixed hex value. Anything that is not a BN object throws an error. With `bitLength` set, it fixes the number to the specified length.

|
| 11 | * ```javascript
|
| 12 | * import BN from 'bn.js';
|
| 13 | * import { bnToHex } from '@polkadot/util';
|
| 14 | *
|
| 15 | * bnToHex(new BN(0x123456)); // => '0x123456'
|
