Summary
In this hour, you learned that Perl's most basic type of data is a scalar. Scalars can be almost any kind of data and are stored in scalar variables. Numeric literals can be represented in many different formats, including integers, and floating-point numbers. String literals are represented by quoted strings, with either double or single quotation marks surrounding them. Also, Perl provides operators for performing string manipulation and basic arithmetic.
