Summary
In this chapter, we started having a more in-depth look at Julia, with a more detailed discussion of various scalar, vector, and matrix data types comprising integer, real numbers, characters, and strings, as well as the operations acting on them.
We then moved on to data types such as rational numbers, big integers, floats, and complex numbers.
We also looked at arithmetic functions, comparing the use of recursive and non-recursive definitions.
Finally, we looked at some complex data structures such as data arrays and data frames, dictionaries and sets, and stacks and queues.
The next chapter follows on by expanding our survey of Julia functions to accommodate passing variable arguments and then considering the type system in greater detail, defining composite data structures, implicit and explicit variable assignment, and the use of parametrization.
