// - depends on: is_float
// - depends on: is_array
// - depends on: is_object
// % note 1: lacks resource type
// % note 2: 1.0 is simplified to 1 before it can be accessed by the function, this makes
// % note 21: it different from the PHP implementation. We can't fix this unfortunately.
// * example 1: gettype(1);
// * returns 1: 'integer'
// * example 2: gettype(undefined);
// * returns 2: 'undefined'
// * example 3: gettype({0: 'Kevin van Zonneveld'});
// * returns 3: 'array'
// * example 4: gettype('foo');
// * returns 4: 'string'
// * example 5: gettype({0: function () {return false;}});
