mathematical calculation order

[sneeuwitje]

very small, but i NEED to know:

Anybody know why Flash doesn't follow regular calculation order:
multiply, divide, add /subtract ?

I thought
var myVar = x/y*z;
would normally be executed as:

x/(y*z)

but Flash does:

(x/y)*z

Funny || am i wrong?

[farafiro]

not funny, it's right
flash executes the * and / before + and -
but if anoy of each group are together it goes ascending (as the order it's written in)

[sneeuwitje]

am i wrong then?

Or what do we call this: a bug or an elephant?

And does anyone know more about what other "not funny stuff" this issue involves?

[farafiro]

bug ???? huh
who said so, it's Math on PCs

[sneeuwitje]

1. math on PCs is different from real math

2. i'm finding out why i never scored > C for maths in school

:eek:

var myVar = x/y*z;
is same as
var myVar = x/(y*z);

every computer(i think) follows same order we learned in school
:)

try this in php
<?
echo "6/8*25=".(6/8*25)."<br>";
echo "(6/(8*25))=".(6/(8*25));
?>
it wil come up with:

6/8*25=18.75
(6/(8*25))=0.03

[magicwand]

oops.......
sorry
i read them wrong
anyway
order of operation:
Inside the ( )
Multiplication and Division which ever comes first.(from your ex. div is first )
addition and subtraction whichever comes first.

sorry about wrong info.

[sneeuwitje]

and at the very basics of it too ...

sorry if this thread annoyed any of you, but it cleared my thinking. I get this way sometimes; wanting to re-discover the wheel and so on - maybe it shouldn't be round at all ...? :D

But enough of this already. It's like farafiro posted in the 1st reply;
* and / are on the same level: which ever comes 1st goes 1st.
and the same for + and - (but that was never a question)

thread closed as far as i'm concerned.

look in Flash Help; theres a whole page for this.
Macromedia/Flash MX/Help/Flash/html/23_appendix_b.html

or through Flash Help:
