 Subject: [PHP-DB] Round a number
 
 
 Hi,
 
 I have a query that returns a number from  culculation in my table. It
 returns say 4.00, 8.75, 0.00, 12.50 etc. How can I get MySQL 
 to return the
 number without any zeros, i.e. 4, 8.75, 0, 12.5 etc?
 
 Thanks for your help

 You can't in MySQL.  At least not that I could figure out.

 In PHP you could write code to do it.

 $float = 4.00;
 $text = (string)$float;
 if (preg_match(/\d+\.0+$/, $text)) {
 list($final) = (int)split(\., $text);
 } elseif {
 ... blah blah blah
 }

 code is untested, I may have written it wrong.

RE: [PHP-DB] Round a number

2003-10-03 Thread Dillon, John
This should do it:

http://www.mysql.com/doc/en/Miscellaneous_functions.html
FORMAT(X,D) 
Formats the number X to a format like '#,###,###.##', rounded to D decimals,
and returns the result as a string. If D is 0, the result will have no
decimal point or fractional part: 
mysql SELECT FORMAT(12332.123456, 4);
- '12,332.1235'
mysql SELECT FORMAT(12332.1,4);
- '12,332.1000'
mysql SELECT FORMAT(12332.2,0);
- '12,332'
