Input Field With Math

logisticdesigns

I am pulling data to another page from an input field.

For example: <? echo "$Input"; ?>

This is a Money $ amount field, how do I make it calculate times (x) 3%. So if they input $100.00, after they hit submit, the input field would come out $103.00.

How do I make it calculate with 3%.

I am new to php, thanks.

The same way you'd do it anywhere else.
$new_price = $old_price+$old_price*(3/100);

I won't pull the data, on the other end it just shows the equation instead of the final data! What am I doing wrong?

<?php echo "$Bill_Amount = $Bill_Amount + $Bill_Amount*(3/100)"; ?>

Outputs

For example: $150 = $150 + $150*(3/100)

Instead of just: $154.5

Well then take off the quotes and PHP won't think it's a string.

That worked fine, sorry about that. Now my other question is, sometimes when it calculates the money it doesn't show it in the manner of $10.00 as an example, it will come out $10.0 or if you put in like $10.03 x 3% it will come out like $10.3309. How do I tell it to not only fill in the "0" if its missing it or not to fill out past the cents for example "09" is not necessary!.

Thanks.

Thanks for the sacrasim, but I'm not building a database!!!
Still need help though!

$number="$".number_format($number, 2, ".",",");

logisticdesigns

Thanks. This is how I have my php code:

<?php echo $Bill_Amount + $Bill_Amount*.029 + .30; ?>

How would I add the "format" script you provided?

Thanks so much guys!

$number = $Bill_Amount + $Bill_Amount*.029 + .30;

$number = "$".number_format($number, 2, ".",",");

echo $number;

logisticdesigns

The code worked perfectly, thanks alot guys..

<?php $number = $Bill_Amount + $Bill_Amount*.029 + .30; $number = "$".number_format($number, 2, ".",","); echo $number; ?>

That's a relief; if you were building a database I would be scared to use it.

You obviously did not read the posts:
decimal; keep the .0 (solution given there, [font=monospace]number_format($num,2)[/font])
Changing 9.99 to 9,99 (solution given there, [font=monospace] result = number_format(14.99+5.00, 2, '.', '');[/font])
format float as currency (solution given there, [font=monospace]$number="$".number_format($number, 2, ".",","); [/font])

If you thought databases were relevant to any of those questions (which I had taken the effort that you didn't bother with to actually look for) then there is a good chance you never actually bothered to read them and learn anything from them. Every one of them suggested using [man]number_format[/man] and every one of them gave explicit examples of its use. Instead, you read the first six words of the first post, fired off "thanks for the sacrasim[sic], but I'm not building a database!!!" and sat around with your thumb inserted for the next (at least) three and a half hours waiting for someone to spoon-feed you with (you'll note, if you read far enough) exactly the same code as had been given in one of the threads you had been given a link for.

None of this speaks well for your abilities as a programmer. Which is why I'd be scared to use any database (or website) that you built.

[PS: You forgot to mark the thread as "Resolved", also.]

Thanks, your attitude is much appreciated and as I say "DOOLEY NOTED"
