Hello, In (info "(elisp) Predicates on Numbers")

 -- Function: plusp number
     This predicate tests whether its argument is positive, and returns
     ‘t’ if so, ‘nil’ otherwise.  The argument must be a number.

 -- Function: minusp number
     This predicate tests whether its argument is negative, and returns
     ‘t’ if so, ‘nil’ otherwise.  The argument must be a number.

 -- Function: oddp integer
     This predicate tests whether its argument is an odd number, and
     returns ‘t’ if so, ‘nil’ otherwise.  The argument must be an
     integer.

 -- Function: evenp integer
     This predicate tests whether its argument is an even number, and
     returns ‘t’ if so, ‘nil’ otherwise.  The argument must be an
     integer.

All these functions are available in cl-lib with "cl-" prefix (not a
scoop, it's always been the case), but not without:

M-: (evenp 2)
eval: Symbol's function definition is void: evenp

You are reading the ELisp manual for Emacs 31, but trying these
functions in Emacs 30:

Emacs 31 adds several functions documented in that node, including
evenp.  They are no longer in cl-lib, but in subr.el.

I see no bug here.

Oops, yes indeed, used the wrong alias when configuring emacs.

Great!

Sorry for the noise and thanks, closing now.
