a)
Explanation of Solution
Interpreting 10110100as an unsigned number:
Step 1: Multiply the given binary number with the positive integers for base 2.
b)
In signed magnitude representation, an extra bit is used to represent the sign of the number. This extra bit is called sign bit.
- The Most Significant Bit (MSB) in the binary number is referred as sign bit.
- In the signed magnitude representation, if the MSB is 0 it is treated as positive sign and if the MSB is 1 it is treated as negative sign.
c)
One’s complement:
The binary numbers can be represented using one’s complement. Here, the value of every binary digit is complemented that is if the value is 1, it becomes 0 and if the value is 0 it becomes 1.
d)
Two’s complement:
Two’s complement is another way of representing the binary numbers. To implement the two’s complements to the number, the given binary number should be one’s complemented and then add 1 to the result obtained after one’s complement.
e)
Excess-127 representation:
To get the excess-127 representation of a given number,
- Add the given number with the 127.
- Convert the obtained value to the binary representation.

- What's wrong with my pseudocode? // The calcDiscountPrice function accepts an item’s price and // the discount percentage as arguments. It uses those // values to calculate and return the discounted price. Function Real calcDiscountPrice(Real price, Real percentage) // Calculate the discount.

- I need help writing pseudocode for calculating class score average by putting in 5 test scores, and showing the average from all 5 inputs and the GPA score.Starting with 3 functions outside of a main module. The functions are getScore(), getGPAPoint(Integer score), and getAverage(). Function getscore is an input for a grade as a class percentage. Function getGPAPoint will calculate the score into a GPA point and return as a float (values of 90-100 as 4.0, 80-89 as 3.0, 70-79 as 2.0, 60-69 as 1.0, and anything below 60 as 0.) Function averageGPA will finally make a call to both previous functions when the user inputs numbers 5 times that then calculates the average (add up all the scores, divide by 5) and the average grade alongside displaying the average GPA. End result is a main module that makes a proper call to the averageGPA function and display its results.
