Bit Level Representations
bit level conversions and representations of numbers.
Guideline for Understanding The Scope of The Project
The size of the data type can be 1, 2, 3, 4, or 6 bytes.
- The signed integers are written as normal integers in the file. (e.g., 3, -5, etc.)
- The unsigned integers are written as integers followed by the letter u. (e.g., 3u, 5u, etc.)
- The floating point numbers are written with a decimal point. (e.g., 3.0, 5.987, etc.)
- If the read data type is signed integer, your program will convert the numbers in the input file using 2’s complement representation.
- If the read data type is unsigned integer, numbers will be converted using unsigned integer representation.
- If the read type is floating point number, you will use IEEE-like format. The number of
exponent bits according to given data size will be like the following:
- if 1 byte (i.e., 8 bits), 4 bits will be used for exponent part
- if 2 bytes (i.e., 16 bits), 6 bits will be used for exponent part
- if 3 bytes (i.e., 24 bits), 8 bits will be used for exponent part
- if 4 bytes (i.e., 32 bits), 10 bits will be used for exponent part
- While calculating the mantissa to get the floating point value, you will only use the first 13 bits of the fraction part (for 3-byte and 4-byte data sizes). You will use “round to nearest even” method for rounding fraction bits to 13 bits. Details about the program are listed below:
- At the beginning of the execution, your program will prompt for the input file
