NIP

RPL command

 

 

 

Type:

 

 

 

Description:

Drops the (n–1)thargument, where n is the number of arguments or items on the stack. (that is,

 

the object on level 2 of the stack). This is equivalent to executing SWAP followed by DROP in

 

RPN mode.

 

 

 

Access:

!°STACK LLNIP

( °is the left-shift of the Nkey).

NOT

Function

 

 

 

Type:

 

 

 

Description: NOT Command: Returns the one’s complement or logical inverse of the argument.

When the argument is a binary integer or string, NOT complements each bit in the argument to produce the result.

•A binary integer is treated as a sequence of bits as long as the current wordsize.

•A string is treated as a sequence of bits, using 8 bits per character (that is, using the binary

version of the character code).

When the argument is a real number or symbolic, NOT does a true/false test. The result is 1 (true) if the argument is zero; it is 0 (false) if the argument is nonzero. This test is usually done on a test result (T/F).

If the argument is an algebraic object, then the result is an algebraic of the form NOT symb. Execute →NUM (or set flag –3 before executing NOT) to produce a numeric result from the algebraic result.

Access: !°TEST LNOT

( °is the left-shift of the Nkey).

…ÃL LOGIC NOT

(Ã is the right-shift of the 3key).

Flags: Numerical Results (–3), Binary Integer Wordsize (–5 through –10)
