specifies the arguments exactly and makes the appropriate references. the zero argument form only works inside a class definition, as the compiler fills in the necessary details to correctly retrieve the class being defined, as well as accessing the current instance for ordinary methods. Note: 1. The super function returns a proxy object through which you can call the method of the parent class or sibling class of the class without displaying the Class Name of the specified parent class or sib

Menu-Type score Query Every school will use the result query. The general query query method is to input the relevant information of the object to be queried and let the system extract the performance data. There are two drawbacks to this approach: 1. need to enter text, for not typing or character entry speed slow people inconvenient; 2. If you entered a typo, a homonym, you can not query the correct results. Today I teach you a new way of querying, you do not need to enter any ch

return value is multiplied by 180/PI (). The return value is expressed in radians (the return value is greater than-pi and less than or equal to pi ). Example: ATAN2 (-2.356194490) equals (3 * pi/4 in radians ). ATAN2 (2, 2) is equal to 0.785398163 (radian pi/4 ). ATAN2 (-180) * 135/PI () is equal to (angle ).
