Equality
and conditional functions

Function
|
Description
|
(= (equal to) numstr
[numstr] ...)
|
Returns
T if all arguments are numerically equal, and returns nil otherwise
|
(/= (not equal to) numstr
[numstr] ...)
|
Returns
T if the arguments are not numerically equal, and nil if the arguments
are numerically equal
|
(< (less than) numstr
[numstr] ...)
|
Returns
T if each argument is numerically less than the argument to its
right, and returns nil otherwise
|
(<= (less than or equal to) numstr [numstr] ...)
|
Returns
T if each argument is numerically less than or equal to the argument
to its right, and returns nil otherwise
|
(> (greater than) numstr
[numstr] ...)
|
Returns
T if each argument is numerically greater than the argument to its
right, and returns nil otherwise
|
(>= (greater than or equal to) numstr [numstr] ...)
|
Returns
T if each argument is numerically greater than or equal to the argument
to its right, and returns nil otherwise
|
(and [ expr ...])
|
Returns
the logical AND of a list of expressions
|
(Boole func int1 [ int2 ...])
|
Serves
as a general bitwise Boolean function
|
(cond [( test result ...)
...])
|
Serves
as the primary conditional function for AutoLISP
|
(eq expr1 expr2)
|
Determines
whether two expressions are identical
|
(equal expr1 expr2 [fuzz])
|
Determines
whether two expressions are equal
|
(if testexpr thenexpr [elseexpr])
|
Conditionally
evaluates expressions
|
(or [ expr ...])
|
Returns
the logical OR of a list of expressions
|
(repeat int [ expr ...])
|
Evaluates
each expression a specified number of times, and returns the value
of the last expression
|
(while testexpr [ expr ...])
|
Evaluates
a test expression, and if it is not nil, evaluates other expressions;
repeats this process until the test expression evaluates to nil
