Type Conversions component
Component to simplify the task of converting data into different bit type variables. Allows conversion between Bytes, Ints, Longs and Floats. Useful when you need to store Ints, Longs and Floats into Byte based memory. Uses a simple 32-bit C Union to overlay the following variable types into the same RAM space. Byte[4], Int[2], Long, Float

Detailed description
The type conversion component overlays several variable types on top of each other using a C code union.
This allows for very efficient conversion between data types without resorting to costly mathematics or bit shifting operations.
Here is an overview of the variable overlay.
Examples
this example converts several different variable types.
