Explicit Type Conversion

If you are dealing with variables of type int, rather than just numbers in code, you need to convert the value of a variable to double or float. This can be accomplished using the following syntax:

There are several ways to explicitly perform type conversion in C++. The previous one is called C-style conversion:

There are also 4 type casting operators:

Most of the time, you only need a static_conversion. We will not discuss other casts in-depth. Here is the syntax:

And here is an example:

We will not cover the difference between all of those. In general, static_cast is preferable since it is more restrictive and can prevent some unexpected behavior with complex data types.
