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 $.
