[PHP] Re: printf and number_format rounding
"Duffy, Scott E" <[EMAIL PROTECTED]> wrote in message
news:[EMAIL PROTECTED]
Are printf and number_format supposed to round?
echo ($hcount-$lcount)/$hilow." ";
echo number_format(($hcount-$lcount)/$hilow,2,'.','');
0.208333 0.21
0.145833 0.15
0.17 0.17
0.083 0.08
Printf ("%.2f",($hcount-$lcount)/$hilow);
Does the same.
It would appear to be. If there is a function to print just to the digit
could you point me in the direction? So I would want 0.20 0.14 0.16
0.08 respectively.

You could have the number_format return an extra digit, and then strip that
extra digit off.
$str = number_format(($hcount-$lcount)/$hilow,3,'.','');
$str = substr($str, 0, 4); // (something like this)

figured that out as well You need to put the number_format($number,2) afterwards Thanks to both you!

Figured out why it wasn't working, but I need to be able to display the 2 decimals afterwards "Ron Allen" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > I am looking at how to format output > > Here is what I have.

[PHP] Re: printf
Use number_format() to put a comma between the thousands $foo = 123456789; print number_format($foo); //will print 123,456,789 Ron Allen wrote: > I am looking at how to format output > > Here is what I have.

[PHP] Re: printf scientific notation?
Thank Richard.
So far, I just punted. My site runs on a dedicated box and doesn't
have to service a lot of users so I just wrote a one line C program
to print a single value using a specified format (default is %.4e)
and use exec() to call it.
printe [format] value
Here's how I encapsulated it:
function printe( $x )
{
$lines = array();
exec( "/usr/local/bin/printe \"".$x."\"", $lines );
return $lines[0];
}
and an example of how I call the function:
fputs( $fp, sprintf( "%8.2f %s %s\n", $this->O_a_time[$i],
printe($this->O_a_height[$i]),
printe($this->O_a_cooling[$i]) ) );
It works well enough for now. Eventually I hope to have time to play
and then I'll come back and figure out a real patch for PHP's printf
to support %e directly.
