Re: [PHP-DB] Round a number
I just realized that this does not work with integers such as 80, so one should add a test condition: SELECT IF( ROUND( mycol ) = mycol, mycol, TRIM( TRAILING '.'

RE: [PHP-DB] Round a number
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' John > I have a query that returns a number from culculation in my table.

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.

[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?
