math>rounding>up

[mrdance]

I have found the function floor that rounds an integer. Is there any function that always rounds up, i.e. 2.1 to 3?

Thanks, Henrik

try this:

$value=2.1;
$value=(int)$value+1;

thanks, but I found the function ceil which rounds fractions up.

🙂 I meant it for "nocontrol".
Looks like a MS tactic:
-Take a float.
-Turn it into an int (chopping off the fraction)
-Add one to the result.

ahh 🙂)

lucky that we have php and ceil then! 🙂

late, but i have to answer....

but first i have some questions:
have you ever programmed in C?
which way the php-rounding function does it?
what's faster, not to code but to run?

now my answer:
no i've never worked for ms.

1. yes.
2. I never bothered to read the sourcecode of php, and I don't think that's in any way relevant here.
3. I have no clue what you mean here.

General note:
I was tought to always check if a function is available in a languages before I start writing by own routines.
