Converting a percentage to a grade; without using the if and else function

0

An interesting question came across my mind: If it is possible to convert a percentage to a Grade(A,B,C,D, or an F). Firstly, there is an easy method to convert a percentage to a Grade; by using an If and Else loop. However, are there also other methods with which this can be achieved? Arrays, shiftin bits, etc... It would be very interesting to see if there are any non-trivial methods to this.

Multiply 100 times your percentage which should be a decimal number? If you elaborate on the purpose of this people be able to think of more ways. There's also a for loop and while loop. Doing an array would also be possible if you gave a list of numbers.

They would be the best way to do this, IMO, since you're just considering *one* variable (i.e. the %) and outputting different values (i.e. the grade) depending on that % variable.

No, I don't think there are non-trivial ways to do it with a standard grading system, other than the obvious ways which have been listed in this thread already. I don't understand the system you listed, but consider that since 90 and 100 are both usually considered A's, you can't really index an array to get the letter 'A' because what indexes would you use? 9 and 10, after division to get the tens digit, are both A's. So your array would not work without a lot of extra work.

Need some help with this Array. I am trying to get the sum of the even numbers and the sum of the odd numbers using a for each loop. I know the answers to what I am trying to achive are sum of even = 84 and the sum of ...

When I execute this progammatically, I get a table with row heights much larger than when I do this manually.

Note : Sel is the Word.Selection object and the Clipboard contains an Excel Table.

public void AddClipboard()
{
Sel.PasteExcelTable(false,false, false);
var t = Sel.Tables[Sel.Tables.Count];
t.AutoFitBehavior(Word.WdAutoFitBehavior.wdAutoFitContent);
}

I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
