Hi,
OK, I'm totally stumped by this. This should be the simplest math
imaginable (addition and subtraction), but PHP is coming up with the
wrong answer!
I've checked on 3 different machines (all linux) running both PHP 4 and
PHP 5.
Here is the code to duplicate the problem:
-
i found the culprit. i remembered, that i use to pass the value with..
number_format($totalCost, 2, ".", ",")
so the values being received by my computation has a "," comma 4,000
so that is why i always get wrong values.
thanks again!

Howdy.
It seems to work fine for me, perhaps you have a typo along the lines
some where.

'don't know what's "the pecent of 20% is" ;) but in decimal
form, yes, it's right. Or, just ".2" or "0.2".

the percent of 20% is = .20 right?
how can i compute the correct value for this?
my $totalCost is $4,000 and when i compute it to .20 using this method..
$shippingestimate = $totalCost * .20;
i get the value for the shippingestimate = $0.8 which is wrong.. it should $800
what seems to be wrong?

Hi!
I'm a little stuck with this simple math problem. I'm trying to get a
number of days in integer, not float.

$UserInputMonth = $UserInput[0];

Lets say I have 11 / 3
answer is 2.667
what if I want to get the remainder of it
so 11 / 3 would be 2
is there a built in function for this in PHP?
kinda like MOD in Visual Basic?
- Thanks
