Built in functions (BIFs) are functions which for some reason are built in to the Erlang virtual machine. BIFs often implement functionality that is impossible to implement in Erlang or is too inefficient to implement in Erlang. Some BIFs can be called - by use of the function name only but they are by default belonging - to the erlang module so for example the call to the BIF trunc - below is equivalent with a call to erlang:trunc.
