title: Hexadecimal Integers (HexInt)
---
StrictYAML can interpret a hexadecimal integer
preserving its value
Example yaml_snippet:
```yaml
x: 0x1a
```
```python
from strictyaml import Map, HexInt, load
from ensure import Ensure
schema = Map({"x": HexInt()})
parsed = load(yaml_snippet, schema)
```
Parsed correctly:
```python
Ensure(parsed).equals({"x": 26})
Ensure(parsed.as_yaml()).equals("x: 0x1a\n")
```
Uppercase:
```yaml
x: 0X1A
```
```python
Ensure(load(yaml_snippet, schema).data).equals({"x": 26})
Ensure(load(yaml_snippet, schema).as_yaml()).equals("x: 0X1A\n")
```
