FUNCTION

# integer.parseHex

```signature
pure static function parseHex(value: text): integer
```

**Deprecated** (for removal): Use 'from\_hex' instead

Parse an unsigned hexadecimal text representation of an integer.

Base prefixes are not supported, so one must write e.g. `integer.from_hex('CAFE')` rather than
`integer.from_hex('0xCAFE')`.

Case is ignored, i.e. `integer.from_hex('CAFE')` and `integer.from_hex('cafe')` are equivalent.

**Parameters**

* **value** — the hexadecimal text to be parsed

**Throws**

* `exception` — if the text representation is ill-formed

Since 0.9.0

**Alias of** [integer.from\_hex](https://docs.chromia.com/pages/rell-stdlib/-rell-system-library/root/integer/from_hex/)
