Develop a plan to design and finally implement a set of functions using C++ that would implement the IEEE standard. Phase 1 will include the literature write up, description of the IEEE 754 floating and a complete description of the functions plan:

1. Functions type void, or any data returning function
2. Type of data passed in to the functions (function parameters or arguments)
3. Type of function parameters (value or reference).
4. Global variables if needed.
5. IEEE 754 single precision layout and its individual parts (sign, exponent, and mantissa) details.
6. The hexadecimal layout.
7. Hand work out a full example from A to Z.
