Limited the number of decimal places returned?

[Clive Sweeting]

I've moved on from functions for the time being, and was playing with do
some maths and date/time manipulation.

Lets say I wanted to show the number of days that have past from Unix
timezero, 1970 whatever it is.

I could show this with

$timestamp = mktime(0,0,0);
$indays = $timestamp / 24*60*60;

Echo $indays;

Hoever that gives me loads of long decimals, which look silly.

But how do I limit the number of decimal points returned by a calculation.
Better still, how do Iround up or down to the nearest whole number?

I do try to read the manual, but I'm afraid a lot of the time I either can't
find what I want, or the code examples given simply confuse me further.

You better get used to the manual and stop overseeing the obvious:

That has to be the fastest reply I've ever had.

And thank you. Note to brain, if you want to round some numbers, someone may
have named the function round....
