Round() issue .... should be straightforward i hope

[Accurax]

Hi guys,

 

I hope this is a simple question.... i just cant find the answer atm.

 

I have a set of cash vluse calculated from a base price and a percentage discount.

 

Now, when this comes out at lets say 12.995 I would like to round this to 12.99 and not 13 as im currently getting .... is there any way of doing this?

 

Really appreciate any help you can give

round(12.995,2)

Assuming you always want to round down the fraction of the penny then multiply by 100, round down, divide by 100:

 

$var = 12.995;
$var = floor($var*100)/100;
echo $var;

 

zenag, that will round to 13. A half rounds up.

round(12.055, 2);    // 12.06

 

Great article here.

Try this

 

$val = 12.995;
$val = number_format($val,2);

Try this

 

$val = 12.995;
$val = number_format($val,2);

 

Also rounds to 13. The number_format() function performs a round if necessary.
