Maths problem

[covertx]

Hi all, you may have read my post regarding bars and values and stuff, well I've got that bit figured out now but as my programme is expanding, so is the number of records being parsed into it!

I'm working out a percentage of 2 groups of people:

Number of people from the UK
Number of people from outside of the UK

etc...

Once the number has been calulated I print a percentage of that value compaired to the other value in the window...

EG-1

1 person from the UK -so the value of this is now 1
0 people from outside the UK -so the value of this is still null (0)

Now I'm working out the percentage as follows: (100 being 100%)

100 / [sum of the values of UK and outside UK] * [the value of UK]

So:

100 / [1]*[1] = 100%

I'm having a problem when the UK or outside the UK value goes above 100 as the percentage for both values drops to 0%... How can this be resolved without the original percentage going above 100?

Thanks for reading, I look forward to reading your suggestions!!

[the value of UK]/ [sum of the values of UK and outside UK] * 100

Thanks for your reply!

I've tried that way before (it makes a lot more sense!) But for some reason it doesn't like doing 2 values, and so sets the final output to 2 0%s!

Any other ideas?

But for some reason it doesn't like doing 2 values

I don't understand what you mean?

eg
UK = 50;
NotUK = 50;

SUM = UK + NotUK; //50 + 50 = 100

PERCENTUK = (UK/SUM)*100 //(50/100) * 100 = 50%
PERCENTNOTUK = (NotUK/SUM)*100 //as above

did you try converting them to floats? if working with integers, when dividing 50 by 100, the result might round to 0.

hope this helped

Sorry I took so long to reply! I've actually sorted out the problem! By using Math.Round and assigning the output value to an integer (int)(... The problem is solved and runs beautifully!

Thanks for your replys though!

Take care
