Primitive Types

This chapter covers the basic types of data available to LFE, upon which primatives rest all LFE libraries and applications.

• Integers
• Floats
• Atoms
• Booleans
• Characters

Each of these types has an LFE test function of the form TYPENAMEp (which wrap the respective Erlang is_TYPENAME function). These are used to perform type checks (especially common in guard expressions). These predicate functions will be covered in their respective type sections.
