Php converts an integer to a floating point type
Method 1: use the floatval () function
The floatval function is used to get the floating-point value of a variable.
Floatval cannot be used with arrays or objects.
Method 2:settype () function
The settype ($var,$type) function sets the variable $var to the specified data type $type.
Description:
The value of $type can be:
"boolean" (or "bool", starting with PHP 4.2.0)
"integer" (or "int", starting with PHP 4.2.0)
"float" (available only after PHP 4.2.0, "double" used in older versions is now disabled)
"string"
"array"
"object"
"null" (since PHP 4.2.0)
The settype () function changes the original variable.
