Dear All
I hope that you are doing well and everything is OK.
I have a question, please:
I have a decimal number stored in a matrix. For example,
Matrix subscripts: 1 2 3 5 6 7 8 9
10
Values: 8 9 8 7 7 9 9 2
7
So, the number is: 898779927
My matrix consists of 3000 cells and each cell contains a number from
0-9. I need to get the number of bits for this string in binary.
However, I cannot convert it to binary as the program will give me out
of range.
Thanks and your response will be much appreciated.
Sincerely,
Kal |

| Matlab (matrix Lab.) So read linear algebra. |

You don't need a program for this, just your brain and perhaps a
calculator or set of math tables (or even a slide rule). It only
requires high-school math.
Hint: break the problem into several steps:
1. What is the largest number you can store in those 3000 cells?
2. How many binary bits does it take to store the number 1? 10? 100?
1000? What is the general formula for "the minimum number of bits
needed to store values from 0 to n"?
3. Apply the formula from #2 to the answer of #1.
Without using any calculating aids at all, I can predict that the answer
is going to be almost 10000 bits. For extra credit: how do I know that?

Is this a class assignment? If not, explain
why you want to do this.
