I've not looked at the toolkit in a while, but I suspect you'd be better off either:
1) pulling the data into a int table then pulling it again into a float table
2) converting your int data using the command Move 32 Bits (in the "Logical" group of commands) which will: "move the internal bit pattern of an integer 32 into a float, or to move a float into an integer 32."
Make sense? There are actually many ways of converting data from one form to another. In the debugger, you can view your data in "hex" to help sort it out. Feel free to share those hex bytes you see vs. what you want/expect to see if you need more help here... I've actually been working on some "converting data types" content and would love any real-world examples you'd like to share!
