Question

In a sensible language ( any of C#/Java/Python) write a program which correctly calculates add, subtract, multiply and divide using our ‘minifloat’ binary format using an algorithm you code yourself.  Some details:

Your program only needs to work on two ‘numbers’ at a time, read those in from a text file – failure to read those values from a text file will result in a grade of 0.   For each ‘number’ store the sign, exponent and mantissa separately.   You can hard code your examples.  

E.g.

Struct minifloat{

Int sign;  // sign, actually 1 bit

Int exponent; // this is the exponent and is 4 bits long (0-15)

Int mantissa;  //this is the fraction part and is 3bits long (0-7), but I would keep the 1. Stored explicitly, so it becomes 0-15 and 4 digits long.  

}

Show testing for all 4 (add, sub, mul, div) with at least 3 examples (and compare to results you do by hand).

Make sure you are error checking for NAN and +/- 0.  

Note:  This is an obviously contrived example, the intent is to force you to think about the algorithm, not to make software that anyone would ever want to use.  

The numbers should be from a separate text file.

Answer 1

1. Using Python open() function to read the file in readbinary mode
2. Cretae IF condition statement to verify input is number or not , if it is number then proceed
3. Convert input number into binary using python's bin() function
4. Create Logical Expretion for ADDITIOn,SUBRACTION, operations
5. Then use bitwise OR,XOR and AND operator to operations for each bit values
6. Store result in rective variables
