You could probably handle that by making `SIM_AI` an expression tag, using the other 2 in its expression.

In the script library:

```python
from java.lang import Float

def convert_to_float(int_val):
	return Float.intBitsToFloat(int_val)

```

expression:

```python
runScript(
	'test.convert_to_float', 0,
	{[.]sources/source}[0] << 16 | {[.]sources/source}[1]
)

```

I think it's cleaner/easier to follow, as it makes `SIM_AI` responsible for computing its value, and I'm willing to bet it's also faster.

edit: Wait, it seems the tag doesn't update when the source values change. I'm thinking it's because they're in an array...  
edit2: nevermind, it did change, but the formatting on the final tag was hiding it.
