need help with an equation in an array

pn46

HI everyone

i can't figure out what's wrong with this one code

Expand|Select|Wrap|Line Numbers

 var a=[1,2,3,4,5,6];

var len=a.length;

var med=len/2;

if (len%2==0)

median=(a[med]+a[med-1])/2;

else

median=a[Math.floor(med)];

alert(median);

and the right answer is 3.5 but why is it when i put it into my code and enter the same number it ends up being 22.5

here my code

Expand|Select|Wrap|Line Numbers

 var med= len/2; // length divided by 2 

if (len%2==0)

median=(new_array[med]+ new_array[med-1])/2;

else

median=new_array[Math.floor(med)];

can someone help me? I can pm the whole code if needed thanks

where did you define new_array? ... when i just replace the code and use new_array as a then it works identical ...

kind regards

thanks alot you're from munich oh i visited there before and absolutely love it.

i assume you should parseFloat() or parseInt() the values in the array or at least when you want to calculate with them ... because they are of type string when you use it from any webinput ...

;) ... yes munich is quite a nice place to live and work ... especially when you like the near mountains. i'm looking forward to the winter and its snow - reminds me to get the board out of its 'summer-sleep' ;)

i tried to parseFloat it

Expand|Select|Wrap|Line Numbers

 if (len%2==0)

  median= parseFloat((new_array[med]+ new_array[med-1])/2);

else

  median=new_array[Math.floor(med)];

but it still doesnt work

Expand|Select|Wrap|Line Numbers

 var data=prompt("Enter your data (separate with a comma)","");

new_array = data.split(",");

then i sorted it
but yeah it's beautiful there i actually went to salzburg and i love it there. I would like to go back to visit I really enjoy my time in Europe. I'm actually considering moving there since the people are so laid back rather than here in the us.

the line:

Expand|Select|Wrap|Line Numbers

median= parseFloat((new_array[med]+ new_array[med-1])/2);

should be:

Expand|Select|Wrap|Line Numbers

median= (parseFloat(new_array[med]) + parseFloat(new_array[med-1]))/2;

kind regards

PS: you certainly cannot find us germans 'laid back' ;) or do you? i agree with the other europeans but not the germans ... or it is just a kind of thing that everybody don't like what he has every day (at least for me) ... so everything that is new or unknown seems to be better then our dayly environment :)
