PHP :: Currency Rounding

Rounding?
How can I round a php var up to the nearest whole? Ie:

$foo = 21 / 10;
$out = magicround($foo);
echo $out;
output = "3"
??

If there isn't a easy way to do this, how about just plain rounding? Let the output be 2.
What will mysql do if I try and put 2.1 into a int(11) column? Round it? Round it up, round it down? Give me an error I want to do some deviding and sqrrooting but I can't have decimals!

Currency
is there any places where i can get som
currency data for free with php ?

Currency
i want to build a script that create US dollar to Philippines Peso.

its auto: 1 USD = "Auto" PHP peso

currency script for this.

Rounding Up
I need to round up a number, e.g.

$tot = 24;
$rows = 10;
$npos = (integer)(($tot / $rows) + 0.5);

Here the answer is '2', but i'm after '3'.

How to do?

Currency
How do I output currency, as the zero on the end of the following value gets cut off:

e.g. £0.50

How do I add a zero, if a zero is expected to appear at the end of the value?

Question Of Rounding
Is there a function in PHP to round numbers up?

Or would i have to implement an if statement?

Precision Rounding
I'm looking into what I need to do to perform accurate financial calculations in PHP.

I didn't really know the details, but I was vaguely aware that there are precision problems with floating point arithmetic. It was more difficult than I expected to find information about that, but I did end up finding a great article on IBM's website: Decimal Arithmetic FAQ.

So it seems that the BCMath functions in PHP could be used to perform the calculations with the necessary precision, except that there doesn't seem to be any rounding function. There is only a scale argument that truncates the result values at a particular number of decimal places. This seems like a glaring omission. You can't use the PHP built in round function because that will convert its argument to a floating point value, making it pointless to use the BCMath functions in the first place.

PHP doesn't really have adequate rounding functions for monetary values anway, including the money_format string function which doesn't even specify how it performs rounding.

So my question is, do you have to write your own rounding function or did I miss something? I've already started writing my own function, because it seems necessary, which will initially support the three types of rounding described in the IBM article -- half-even (Banker's), half-up, and down.

Rounding Problem
If I use round(1.95583, 2); I would get the perfect result of 1.96 for my
currency. But if I round(1.9) I would just get 1.9. Is there a function or
solution so it would always round with 2 digits for a currency?

XML Currency Script
I have a table in my database that has 4 different currencies in it (I plan to add more when i have this xml update script done). This has 4 fields, 2 of which are code (eg USD, JPY) and multiplier (USD is taken as 1, and the rest are multiplied from there). Now, I would like to automatically update these currency multipliers using this xml data feed:

"http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml"

The only problem is, i dont know where to start with it. Now if anyone could help me either create an array from this data (so i could use $cymulti['USD'] would equal the rate from the data feed that had the currency USD) or create individual variables such as $USD would equal the rate from the data feed for the currency USD).

Rounding Numbers
I am having trouble getting a script to display 2 decimal places when two numbers are added or multiplied.

I need the script to display 15.70 + 5 as 20.70 not 20.7 and 7.5 * 1.25 to display 9.4 not 9.375

Currency Formatting
i'm trying to format the output of a record in access, which i am
pulling from through php (odbc) and the formatting is set at 4 decimal
places, which i don't want. i want currency and no decimal places.
I was trying to use this example, but i have no bloody idea howo to use it.
or where to put it for that matter:

<?php

$number = 1234.56;

// let's print the international format for the en_US locale
setlocale(LC_MONETARY, 'en_US');
echo money_format('%i', $number)."
";
// USD 1,234.56

?>

Currency Symbols
I have a problem, we use a microsoft (mssql) product at work which stores currency symbols in the database.

Now when I retrieve these symbols from the database and try to echo them to the screen using php I just get a funny square box symbol instead of the actual currency symbol. Any idea on how I can get the symbols to show correctly?

Format Currency
I want to take a variable and make sure that I output to the browser in dollar format ie if I set $price=100. I want to make sure that $price appears as 100.00. in turn make sure that when $price=100.97 is outputted as 100.97

Rounding A Number?
how can I make this value:

$fuel = "19312.92";

end up looking like this:

$fuel = "193";

And if possible, always insert a ZERO in front of the result, so that it ends up looking like this:

$fuel = "0193";

Rounding Down Function
I know the function to round. I was wondering is there anyway to round down?

Because the round function currently rounds (for example)4.5 to 5, whereas i want 4.5 to be 4.
Can this be done?

Or will it just be easier for me to -0.1 from the number first?

Format Currency With More Than 2 Decimals
I've tried to use both round and money_format but I can't seem to get what i what.

I have a shopping cart on my web site and I had the tax to the subtotal for calculating the total.

However the following problem arises when using round():
$13.2818
becomes $13.28 (should be $13.29)

$13.2772
becomes $13.28 (works fine)

Is there another function that will ALWAYS round up after X number of decimals?

Resulting Number Rounding Up!
how I can get a resulting number to always be rounded up. So if I am dividing a number of columns by two, I want the resulting number to always be rounded up if it returns any remainders. Does anyone know how I can do this. I tried using the ceil () function but with no luck.

Numeric Currency To Words
I have a program which calculates some transactions and giving the total as numbers. for eg. 1000.00. I want to display it in words also. Like (One thousand only)..

Rounding Numbers To The Next Highest 50
I can use the round(), ceiling() and floor() functions to make numbers upto the next whole number (3.6 -> 4 etc.) but how do I round a number to the next highest 50?

e.g.

36.3 -> 50
83.2 -> 100
-26.5 -> -50
-94.0 -> -100

Clean Currency Input
I wrote the following function as a "cleaner" for a currency input:

function is_currency($v) {
//returns a string with only the numbers for a currency format
$v = str_replace("$", "", $v);
$regex = '/(?:([0-9]+)|.)/'
if(preg_match($regex, trim($v) ) ){
$v = $v + 0.00001;
if (is_float($v)) {
return round($v, 2);
}
}
else {
return 0;
}
}

I want users to be able to put in things like:
NZ$12.34
$12.34
12
12.3456
1,002.23
and it should always translate into a number with two decimals (e.g. 12.34
or 12.00)

I am sure that this is probably the clumsiest way ever to do this. How can
I improve this function?

PS despite numerous efforts I am still super weak on regular expressions. I
can only copy them and not write them myself.

Rounding Number Question?
Anyone know a ood way to round a number to nearest .5?

1 Decimal Place Without Rounding
If I have a float number of say 3.478399 How can I reduce the number to 1 decimal place without rounding?

I've tried it will sprintf, but it rounds the 4 to a 5 which I want to avoid.

$float_number = 3.478399;
$new_float_number = sprintf ("%0.1f",$float_number);

Output returns 3.5 when really I need it to be 3.4

Language And Currency Changing Script ?
I am asking this on behalf of a friend who is - as I am - completely
ignorant of php. Almost.

He has CartWeaver shopping cart. The php version. He need to be able to
allow users to swap currency and language with a click, but still have
the cart connected to one single and the same data base.

He has been in touch with the developers, and their reply is that the
feature might be included in next version.

Question is: Can he in some way apply this in a way himself with some
link(s) to extra language and currency files? If so, how should it be
done? Are there any samples out there? (we have both searched the web
for a month - in vane).

Rounding A Variable To Nearest Integer?

How Do I Insert And Display Currency In PHP/MySQL?

Truncate A Decimal Pointed Figure Without Rounding ...

I know I'm being stupid here, but it's really bugging me. The number before
the decimal point could 0 - 999

Data Field With Currency Not Sorting Accurately
I have a datatable with a varchar field know as "price". At this time I have 3 rows in it; they are as follows: $ 18,500 $19,500 and $ 9,500. The problem is that when I try to sort in either ascending or descending order; it does not sort right. I know the problem lies in the $ 9,500, because I added a zero in front of the 9,500 (like this: $ 09,500) and it sorted fine. At first I thought it may have had something to do with the dollar sign, but it didn't because I removed and tested it without dollar sign and still had the same problem.

What I want to know is, how I can make datatable sort accurately with putting a zero in front of the 9,500. I tried to use a CSS style to cover up the zero, but when I did that, datatable still would not sort the right way. MySQL code in my web page is accurate, because you can take the $ 9,500 and add a 5 digit number and it works fine.
