void loop() { 
  int t = timestwo(val); 
  Serial.println(t); 
} 
 
int timestwo(int dVal) { 
  dVal = dVal * 2; 
  return dVal; 
}

Description   Keyword used to indicate the value to return from a function. The value being returned must be the same datatype as defined in the function declaration. Functions declared with void can't return values and shouldn't include a return value. The keyword return may also be used to break out of a function thus not allowing the program to read the remaining statements (see the third example above).
   
Syntax
