<=
  | 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, and 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)            => T
(<= 1 2)            => T
(<= 2.0 1.99)       => NIL
(<= 1 2 3 3)        => T
(<= 1 2 3 3 2)      => NIL
(<= "aa" "aa")      => error: bad argument type
(setq a 12 b 99.9)  => 99.9  ; set up A and B with values
(<= a b)            => T
(<= b a)            => NIL
