Non-alphabetic Functions Reference (AutoLISP)

These AutoLISP functions all start non-alphabetic or numeric characters.

Functions

• + (add)

  Returns the sum of all numbers

• - (subtract)

  Subtracts the second and following numbers from the first and returns the difference

• = (equal_to)

  Compares arguments for numerical equality

• /= (not equal to)

  Compares arguments for numerical inequality

• / (divide)

  Divides the first number by the product of the remaining numbers and returns the quotient

• * (multiply)

  Returns the product of all numbers

• *error*

  A user-definable error-handling function

• *pop-error-mode*

  Error-handling function that ends the previous call to *push-error-using-command* or *push-error-using-stack*

• *push-error-using-command*

  Error-handling function that indicates the use of the command function within a custom *error* handler

• *push-error-using-stack*

  Error-handling function that indicates the use of variables from the AutoLISP stack within a custom *error* handler

• > (greater_than)

  Returns T if each argument is numerically greater than the argument to its right; otherwise returns nil

• >= (greater_than_or_equal_to)

  Returns T if each argument is numerically greater than or equal to the argument to its right; otherwise returns nil

• < (less_than)

  Returns T if each argument is numerically less than the argument to its right; otherwise nil

• <= (less_than_or_equal_to)

  Returns T if each argument is numerically less than or equal to the argument to its right; otherwise returns nil

• ~ (bitwise_not)

  Returns the bitwise NOT (1's complement) of the argument

• 1- (decrement)

  Decrements a number by 1

• 1+ (increment)

  Increments a number by 1
