Trying to get a point two decimal outcome

[JudgementDay]

I want to compute 150 + 20.95 * 1.01 + .5 so I get '171.65'.

 

echo (150 + 20.95 * 1.01 + .5); gives me '171.6595'.

 

I tried echo number_format(150 + 20.95 * 1.01 + .5, 2);, but I got '171.66'.

 

How can I go about getting '171.65'?

((int)((150 + 20.95 * 1.01 + .5) * 100)) / 100;

 

Solved.

I'm having a little trouble when using the solution with my own code. I am getting the error 'unexpected ;':

 

$grandtotal = ((int)(($_SESSION['order']['contentvalue'] + $_SESSION['order']['deliverycost'] * 1.01 + $_SESSION['order']['paymentsurcharge'])) / 100;

 

I can understand why ';' is unexpected?

Count the parentheses.

I don't know what that means.

 

Anyway, the problem is now solved:

$grandtotal = ((int)(($_SESSION['order']['contentvalue'] + $_SESSION['order']['deliverycost'] * 1.01 + $_SESSION['order']['paymentsurcharge']) * 100)) / 100;

[JudgementDay]

$grandtotal = ((int)((450 * 1.01) * 100)) / 100;

gives me '454.5'.

 

Is it possible to get '454.50' instead?

I don't know what that means.

It means you count every ( you have and every ) you have.  If the number doesn't match, then you have a problem.

 

When you start dealing with lines like that, it often is better to fill in a few temporary variables and use those.

$subTotal = $_SESSION['order']['contentvalue'] + $_SESSION['order']['deliverycost'] * 1.01;
$total = $subTotal + $_SESSION['order']['paymentsurcharge'];
$total = floor($total*100)/100;

 

Much easier to read and follow;

number_format should take care of that for you.

Hey bro,

 

I find temporary variables cause spaghetti and crufts up my code.

 

Hey, I found a solution to my problem. Its beyond my capacity to understand how it works, but all I know it does.

I don't have time to learn how it works. I am badly behind schedule.

 

$formula = ((int)((1 + 2 * 1.01 + 3) * 100)) / 100;
$grandtotal = sprintf("%01.2f", $formula);

 

Anyway, gotta run. Just came back to share the solution and mark as solved.

P.S (INT) may not be neccessary
