type/builtin

 Calling Sequence type(e::anything, 'builtin')

Description

 • An expression is of type builtin if it is a procedure with option builtin. (See option.) This type helps to identify those procedures that are implemented in the Maple kernel, rather than the library.
 • It may be used with anames to list all builtin procedures. For example anames(builtin).
