+## Decode properties: numbers
+All values are assumed to be strings when parsing properties, but you can use the `from_yaml` operator on all the strings values to autoparse into the correct type.

+Given a sample.properties file of:

+a.b = 10
+```
+then
+```bash
+yq -p=props ' (.. | select(tag == "!!str")) |= from_yaml' sample.properties
