Converting types

Integers, floats, and strings are the most common data types you will encounter when working with Julia. Certain operations can only be performed on certain data types, and some operations work differently based on the data type.

For example, in Julia 3*2 will return 6, but "3"*"2" will return "32". These kinds of bugs can crash your code or ruin your analysis, so it is important to know how to convert between types.
