Number Formating An Array's Output??

Anon

Hello,

If I have an array which outputs a product sale price (newcost) after adding a percentage to the product's cost in the database. Which ends up creating a price of something like $452.3296. How can I format the array's output to two decimal positions.

Here is parts of the query code:

$charge = (1+ ($percent/100));
query="select...cost*$charge as newcost where....";

echo this: .$row[newcost]

I can use number_format on $charge, but that won't format it when it gets multiplied by the cost. newcost is what needs to be formated - can I do that to the echo ouput above?

Try the following

round
(PHP 3, PHP 4 )

round -- Rounds a float
Description

double round (double val [, int precision])

Returns the rounded value of val to specified precision (number of digits after the decimal point).

$foo = round (3.4); // $foo == 3.0
$foo = round (3.5); // $foo == 4.0
$foo = round (3.6); // $foo == 4.0

$foo = round (1.95583, 2); // $foo == 1.96

Note: The precision parameter is only available in PHP 4.

But, how can I use the round function with the output of the array? I need to know the proper syntax for using round with the array outputs - round(.$row[newcost], 2) I get pharse errors.

u can use array with round

round($row[newcost], 2);

example:

<?
$i[0]=10.90909;

echo$value=round($i[0],2);

answer will be 10.91;

try this out
