Function hexToNumber

Convert a hexadecimal string to a number. This verifies that the string is a valid hex string, and that the resulting number is a safe integer. Both "0x"-prefixed and unprefixed strings are supported.

To convert a hexadecimal string to a bigint instead, use hexToBigInt.

Example

hexToNumber('0x0'); // 0
hexToNumber('0x1'); // 1
hexToNumber('0x10'); // 16

Returns

The number.

Throws

If the value is not a valid hexadecimal string, or if the resulting number is not a safe integer.
