Curently using decimal point for percent, how can I use the percent sign?

[chinwan]

I have a script that is calculating how much the credit card fee was to process a payment.

I am going to be use relatively fixed values for the credit card percent.

 

As of now, I have the percent written as a decimal point (".275") , but I would rather have it as a "2.75%". How would I restructure my statement:

$creditcardpercent = ".275"

$balance = $order * $creditcardpercent

 

That it will calculate it properly?

 

 

Thanks

Where do you have it written with decimal point? In the database?

 

I guess you mean 27.5% and not 2.75 in this case?

multiply the decimal number by 100. this will give you a percent figure i.e.

 

$number = .376;
$percent = $number*100;
echo $percent."%";  //display 37.6%

Then you will have to adjust your calculations though so that you don't multiply with the number of percents. That will get expensive

You cannot use like

$per = 5.35% because the per cent sign is a modulus operator.

 

$creditcardpercent = .275 *100;
$balance = $order * $creditcardpercent;

// or
$creditcardpercent = .275;
$balance = $order * ($creditcardpercent * 100);

Perhaps I misunderstood you. Of course you not user "2.75%" in calculations and you must not store the value that way in the database but you may display if on your pages in any format you wish. Whether you store it as 2.75 or 0.0275 doesn't really matter, you can do format them in anyway you like when producing html output.
