ttmt Posted December 8, 2012 Share Posted December 8, 2012 Hi all I have simple page here to illustrate my question. http://www.ttmt.org.uk/forum/discount/ It's a function that calculates a percentage of a given number. My problem is if the percentage calculated ends with a zero it isn't displayed as in the second number on the example page. I would like the second example to display £5.50 <!DOCTYPE html> <html> <meta charset="UTF-8"> <title>Title of the document</title> <style type="text/css"> *{margin:0;padding:0;} #wrap{margin:50px;} h3{display:block;font:1.2em Helvetica, sans-serif;color:#555;margin:0 0 15px 0;} .deletePrice{margin:0 20px 0 0;text-decoration:line-through} .discountRed{color:red;} </style> </head> <body> <div id="wrap"> <?php function item($price, $discount){ if($discount > 0){ $normPrice = $price; $normPriceDelete = "<span class='deletePrice discountRed'>£$normPrice</span>"; $price = ($discount/100)*$normPrice; $discountPrice = "<span class='price'>£$price</span>"; global $priceBlock; $priceBlock = "<span class='price deletePrice'>£$normPrice</span><span class='price discountRed'>£$price</span>"; echo "<h3>".$priceBlock."</h3>"; }else{ global $priceBlock; $priceBlock = "<span class='price'>£$price</span>"; echo "<h3>".$priceBlock."</h3>"; } } item(22,26); item(22,25); ?> </div> </body> </html> Link to comment https://forums.phpfreaks.com/topic/271749-missing-zero-on-discount-calculation/ Share on other sites More sharing options...
