i am reading a PHP ebook and it tells me how to change the type of a string..and i m doing what the book says but it keeps saying that the string is A "STRING" rather then a DOUBLE

here is the code
PHP Code:
define(SPACE, "<br/>");
define (A, " ") ;
$number = 1;
$number2 = "3.14";

print
gettype(number2). SPACE;
settype($number2, double);
print
gettype(number2). SPACE;

bool settype ( mixed &var, string type )

Set the type of variable var to type.

Possibles values of type are:
"boolean" (or, since PHP 4.2.0, "bool")
"integer" (or, since PHP 4.2.0, "int")
"float" (only possible since PHP 4.2.0, for older versions use the deprecated variant "double")
"string"
"array"
"object"
"null" (since PHP 4.2.0)

Make it a float? I've never heard of double before.

It also needs quotes.

settype($number2, "float");

Also, I think you need to make it gettype($number2).. you don't have the $.
