Floating point restriction

[sake]

Hey Everyone,
Just wondering how I would restrict the amount of digits displayed when printing decimal floating point numbers. Not so it wouldnt calculate that many digits, just so it wouldnt display all of them.Hope that makes sense...

Thanks in advance,
Sake

you can try
round()
or if it just for display do something like

$floatNumber = 10.0600000009;
echo substr($floatNumber,0,-7);   // show 10.060

Hi.

Yea, round() would do the trick.

Try something like:

$myNumber = 123.456789;
echo round($myNumber, 3);
# Which should echo: 123.457
 

Or if you want to handle it as a string, try looking into the explode, substr and implode functions.

Thanks alot for the help, the round() function works great. :-)
