How Do You Truncate A Number?

Hi,

How do you truncate or round a number to a set no. of decimal places in PHP?

eg

16.666666666667 => 16 or 16.7

I have looked for a truncate function and a rounding funtion but can't find one.

Any help would be great,
Thanks

round(); maybe?

... or number_format()

so it would be

PHP Code:


echo round(16.66666667);

This will actually give you 17

PHP Code:


echo round(16.666667, 1);

would give you 16.7

Thanks for the replies. I don't have time to look at them right now but they look like what I need.

Thanks
