[RESOLVED] Convert number

[NZ_Kiwis]

How can I convert

0.0468162756901

to Say

0.046

[NZ_Kiwis]

$diff2 = 0.0468162756901;

$chars = 5;
$diff2 = substr($diff2,0,$chars);

I wouldn't recommend that - wouldn't

floor($diff2, 3);

be better

It might be better if [man]floor/man accepted a second parameter. 😉

You could do it arithmetically with:

$test = 0.0468162756901;
echo round($test - 0.0005, 3); // 0.046

Although usually you would tend to round things like that:

$test = 0.0468162756901;
echo round($test, 3);          // 0.047

But since I don't know the underlying requirement, who knows?

We're not supposed to know the underlying requirement, just give the poster every angle they didn't even think about 🙂

of course if you wanted to do floor() you could also do:

( floor($x * 1000 /* move left 3 places */) ) / 1000

what would we do without posters posting general posts? we couldn't have these conversations!
