dividing and getting only the remainder

Fking

what's the function in php, for dividing and getting only the humber after the decimal point
?

echo (5%3); //yields 2

thanks
now i need to get only the whole number

laserlight

What exactly do you want:

For example:

9/4 = 2.25
9/4 = 2R1

Do you want 2, 1, or 0.25?

Fking

i need 2

laserlight

Use [man]intval/man on the result.

Fking

i was thinking that there is something like % but with the opposite effect
like this was in pascal

but anyway intval already did the job :>

thanks

couldn't you do this

var1 = 5;
var2 = 3;

r = var1%var2;

var1 = var1 - r;

whole = var1/var2;

Yeah Zudo, you could do that....

You could put it all into a function too, to make it easer to call later:

<?
$var1 = 23;
$var2 = 7;

function divideme($var1, $var2){
  global $r, $whole;

  $r = $var1%$var2;
  $var1 = $var1 - $r;
  $whole = $var1/$var2;

  return $r; $whole;
}

divideme($var1, $var2);

echo $var1."/".$var2."=";
echo $whole."R".$r;

// Outputs  23/7=3R2
?>

Of course, the numbers get screwed up if $var1 is smaller than $var2, so you would want to build in some error checking to make sure $var1 is larger than $var2. (Or you could just manipulate the function to account for this, and do the proper math to reflect it.)

Well, yes, you could do it using a long way.
But there's no point where there's a shortcut.

You can just get the remainder using the modulo operator, and just get the integer quotient by taking the integer value of the quotient.
It works simply because the quotient can be represented as a mixed number (as opposed to its actual decimal/floating point representation) where you wish to ignore the fraction component.

You dont need error checking, aside from say, checking for division by 0, which you have to do either way.

Yeah laserlight, I am not saying this is the best route... It is a good learning experience though...

Simple for learning how to handle math functions, or writing simple functions, or whatnot.

Why reinvent the wheel right? I agree with you.
