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
See setq.
