[SOLVED] trouble with round fonction

[nec9716]

When I run that:

 

$totalr = round(10.333333, -2);

 

 

I should have something but the print value of $totalr is always 0.....I was thinking to see something like 10.33 but no luck

Try this:

 

 

$totalr = round(10.333333, 2);

Why would you want -2 decimals? That's not possible.

Actually it is, if he had round(10456,-2) it would round to 10500. He just doesn't have enough digits.

I really apologize...type mismatch.....

i have write that:

$totalr = round(10.333333, -2);

 

but ....there no "-"

 

$totalr = round(10.333333, 2);

 

 

sorry

That code works, I just tested it.  It results 10.33

[nec9716]

yes ...just try it as well.....

 

now if I want to round a value of a variable like:

 

$total = $row['total'];

$totalr = round($total,2);

 

is that the way to write that?

 

 

 

thank you .....

Looks like you just did.  That should work.  If it's not parsing it as a float try this:

 

$total = $row['total'];
(float) $total;
$totalr = round($total,2);

thank you it work fine now....

 

 

thank again
