[PHP] rounding average to one decimal point

2004-05-10 Thread Adam Williams
Hi, I have a randon group of numbers I need the average of.  When I add 
them up and divide by how many there are and print the result, I get a 
lot of decimal places.  The number comes out to look like 29.3529411765, 
but I don't need that many decimal places.  rounding to one decimal place 
will be fine.  anyway to trim off the excess decimal values?

Try the round() function? :)

ceil() and floor() might help if you decide you don't want the extra
decimal places too.

How about round()

echo round(1.95583, 2);  // 1.96
echo round(1241757, -3); // 1242000
