SYNTAX

(> <expr1> <expr2> ... )
        <exprN>         -       a numeric expression

DESCRIPTION

The > (GREATER-THAN) operation takes an arbitrary number of numeric arguments. It checks to see if all the numbers are monotonically decreasing. T is returned if the arguments are numerically, monotonically decreasing, NIL is returned otherwise. For two arguments, this has the effect of testing if <expr1> is greater than <expr2>.

EXAMPLES

(> 1 1)                                 ; returns NIL
(> 1 2)                                 ; returns NIL
(> 2.0 1.99)                            ; returns T
(> 3 2 1)                               ; returns T
(> 3 2 2)                               ; returns NIL
(> "aa" "aa")                           ; error: bad argument type
(setq a 12) (setq b 999.999)            ; set up A and B with values
(> a b)                                 ; returns NIL
(> b a)                                 ; returns T
