Running: $ ./main

C-based bit-level FP16/FP32 operator for designing and verifying a 16bits/32bits floating pointer hardware operator.

1. FP32 Addition
2. FP32 Subtraction
3. FP32 Multiplication
4. FP32 division (occur bit error at last bit of mantisa due to round-up)
5. FP16 Addition/Subtraction (support normal and subnormal)
6. FP16 Multiplication (support normal and subnormal) TODO list
7. add FP16 operator (Division)
