• (<= &rest numbers) [Function]
   

  Returns T if NUMBERS are in nondecreasing order; NIL otherwise. Vectorized.

• (= &rest numbers) [Function]
   

  Returns T if NUMBERS are all equal; NIL otherwise. Vectorized.

• (/= &rest numbers) [Function]
   

  Returns T if NUMBERS no two adjacent numbers are equal; NIL otherwise. Vectorized.
