title: Integers (Int)
---
StrictYAML parses to a YAML object, not
the value directly to give you more flexibility
and control over what you can do with the YAML.
This is what that can object can do - in many
cases if parsed as a integer, it will behave in
the same way.
Example yaml_snippet:
```yaml
a: 1
b: 5
```
```python
from strictyaml import Map, Int, load
from ensure import Ensure
schema = Map({"a": Int(), "b": Int()})
parsed = load(yaml_snippet, schema)
```
Parsed correctly:
```python
Ensure(parsed).equals({"a": 1, "b": 5})
```
Has underscores:
```yaml
a: 10_000_000
b: 10_0_0
```
```python
Ensure(load(yaml_snippet, schema).data).equals({"a": 10000000, "b": 1000})
```
Cast with str:
```python
Ensure(str(parsed["a"])).equals("1")
```
Cast with float:
```python
Ensure(float(parsed["a"])).equals(1.0)
```
Greater than:
```python
Ensure(parsed["a"] > 0).equals(True)
```
Less than:
```python
Ensure(parsed["a"] < 2).equals(True)
```
To get actual int, use .data:
```python
Ensure(type(load(yaml_snippet, schema)["a"].data) is int).equals(True)
```
Cannot cast to bool:
```python
bool(load(yaml_snippet, schema)['a'])
```
```python
:
Cannot cast 'YAML(1)' to bool.
Use bool(yamlobj.data) or bool(yamlobj.text) instead.
```
