<=

Type:	-	function (subr)
Source:	-	xlmath.c

Syntax

(<= expr1 expr2 ... )

exprN - a numeric expression
returns -  T  if the results of comparing the expressions are all true, NIL otherwise

Description

The '<=' [less-than-or-equal] function takes an arbitrary number of numeric arguments. It checks to see if all the numbers are monotonically non-decreasing.  T  is returned if the arguments are numerically, monotonically non-decreasing, NIL is returned otherwise. For two arguments, this has the effect of testing if 'expr1' is less than or equal to 'expr2'.

Examples

(<= 1 1)                      ; returns T
(<= 1 2)                      ; returns T
(<= 2.0 1.99)                 ; returns NIL
(<= 1 2 3 3)                  ; returns T
(<= 1 2 3 3 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 T
(<= b a)                      ; returns NIL
