Function numToHex

numToHex(val: NumLike): `0x${string}`
Converts a NumLike value into its hexadecimal string representation, prefixed with 0x.
Parameters
- val: NumLike
  The value to convert, which can be a string, number, bigint, or HexLike.
Returns `0x${string}`
A Hex string representing the number.
Remarks
This function returns the direct hexadecimal representation of the number, which may have an odd number of digits. For a full-byte representation (an even number of hex digits), consider using numToBytes, numLeToBytes, or numBeToBytes and then converting the resulting byte array to a hex string.

Throws
If the normalized numeric value is negative.
Example
```
const hex = numToHex(4660); // "0x1234"
const oddLengthHex = numToHex(10); // "0xa"
```
