**//Number comparison operators//**

Comparison between numbers, return ''T'' or ''NIL''. Accept mix of integers and floats. Accept any number of arguments, but for trivial zero or single argument always return ''T''.

 ''='' 

Tests if all arguments are equal.

<code lisp>
>(= 1 1.0 (- 2 1))   ; all are 1
T
</code>


 ''/=''

Tests if no argument is equal to another.

<code lisp>
>(/= 1 2 3 1.0 4)   ; there is 1 twice  
NIL
</code>

''<'' 

Tests if arguments are ordered from smallest to largest.

<code lisp>
>(< 1 2 3 3.0 4)   ; there is 3 twice  
NIL
</code>

''>'' 

Tests if arguments are ordered from largest to smallest.

<code lisp>
>(> 4 3 2)    
T
</code>

''%%<=%%'' 

Tests if arguments are ordered so the next argument is at least the same or larger than previous.

<code lisp>
>(<= 1 2 3 3.0 3 4) 
T
</code>

''>=''

Tests if arguments are ordered so the next argument is at most the same or smaller than previous.

<code lisp>
>(>= 1 2 3 3.0 3 4) 
NIL
