[SOLVED] Manipulating integers

[shamuraq]

Hi All,

 

I would like to add a positive sign "+" infront of a positive integer. Is there a proper syntax to it without the <echo> function so that php still treat it as integer rather than a variable for further mathematical function to take place?

 

-thanx all

No, there isn't.

Use integers for calculations. Convert to string when displaying.

do a function

 

function format($number){

    if($number > 0) return "+".$number;

    else if($number < 0) return $number;

    else if($number == 0) return $number;

}

 

 

echo format(1);

But it's not an integer anymore

So how do i convert it to string?

Just adding a "+" to it converts it to a string.

 

Also you can just use sprintf instead of nadeemshafi9's format().

 

$a = "2";

echo sprintf("%+d\n", $a);
echo sprintf("%+d\n", -$a);

%d will just be replaced by a signed integer. That should be a fairly simple concept and it's consistent over all languages that has a printf-ish function.

Thanx again Daniel0
