float reduced

[Thierry]

Hello,

I'd like to write a function who return a float with only two digits
after the point.

For instance : 12.34567 -> 12.34

Any help would be welcome

Tkx, Titi.

That *rounds* the value instead of returning the float with only the
last to digits of it (ok actually Thierry asked for a function which
returns *a* float (function give($float) { return 3.14; } would do it)).

I think

function cutFloat($float)
{
return (float) floor($float*100)/100;
}

is what Thierry really searches.

When you would have bothered to look at the manual page, you would have
noticed that the round function accepts an optional second argument to
indicate the precision.

I knew this argument but the function still *rounds*.
That means:

3.145 --> 3.15
3.144 --> 3.14

My function gives:

3.145 --> 3.14
3.144 --> 3.14
