Re: [PHP] PHP 4.2.2 Float->Mysql addition problem

[Andrei]

	When working with floats with php/mysql I had problems too... When 
summing amounts I had errors so my solution was using decimal (20, 10) 
type into mysql for storing amounts and when using sums in php I used bc 
functions. This way u get exact calculations (depending on bcscale() 
parameter.

Ok here is the problem:
I try to summary float values from my database (mysql) in PHP.

code:

$sql = "SELECT * FROM somwehere WHERE 1";
$result = mysql_query($sql);
while ($assoc = mysql_fetch_assoc($result))
  {
    //adding values
    $sum = $sum + $assoc["floatval"];
  }
echo $sum; // echoes an INTEGER VALUE O_o

echoing the mysql value it is float like "123.45"

The type of the mysql value is "string"
setting the type to float doesnt help (settype())

Any ideas?
