A brief about multiple dispatch

A function is an object, mapping a tuple of arguments using an expression to return a value. When this function object is unable to return a value, it throws an exception. For different types of arguments, the same conceptual function can have different implementations.

For example, we could have a function to add two floating point numbers and another function to add two integers. But, conceptually, we are only adding two numbers. Julia provides a functionality through which different implementations of the same concept can be implemented easily.

The functions don't need to be defined all at once; they are defined in small abstracts. These small abstracts are different argument type combinations and have different ...
