HP 50g Graphing, 48gII Graphing Nip, Not, Noval, Access ! Test L not Is the leftshift of the Nkey

Command:	NEXTPRIME(145)
Result:	149
See also:	ISPRIME?, PREVPRIME
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 leftshift of the		Nkey).
	ISTACK LLNIP
Input/Output:
		Level 2	Level 1		Level 1
		obj1	obj2	→	obj2
	333 222
Example:		1 NIP returns 333 1

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 leftshift of the Nkey).
…ÃL LOGIC NOT	(Ã is the rightshift of the 3key).

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

Input/Output:

Level 1/Argument 1		Level 1/Item 1
#n1	→	#n2
T/F	→	0/1
“string1”	→	“string2”
'symb'	→	'NOT symb'
