HP 48gII Graphing, 50g Graphing Amort, Principal Interest Balance, TVM, TVMBEG, TVMEND, Tvmroot

AMORT

Type:	Command
Description:	Amortize Command: Amortizes a loan or investment based upon the current amortization
	settings.
	Values must be stored in the TVM variables (I%YR, PV, PMT, and PYR). The number of
	payments n is taken from the input together with flag –14.
Access:	@& Î TVM AMORT			(Î is the leftshift of the		7key).
Flags:	Financial Payment Mode (–14)
Input/Output:
		Level 1/Argument 1		Level 3/Item 1	Level 2/Item 2	Level 1/Item 3
		n	→	principal	interest	balance

AND	Function
Type:
Description:	And Function: Returns the logical AND of two arguments.

When the arguments are binary integers or strings, AND does a bitbybit (base 2) logical comparison.

•An argument that is a binary integer is treated as a sequence of bits as long as the current wordsize. Each bit in the result is determined by comparing the corresponding bits (bit1 and bit2) in the two arguments as shown in the following table.

bit1	bit2	bit1 AND bit2
0	0	0
0	1	0
1	0	0
1	1	1

•An argument that is a string is treated as a sequence of bits, using 8 bits per character (that is, using the binary version of the character code). The two string arguments must have the same number of characters.

When the arguments are real numbers or symbolics, AND simply does a true/false test. The result is 1 (true) if both arguments are nonzero; it is 0 (false) if either or both arguments are zero. This test is usually done to compare two test results.

If either or both of the arguments are algebraic expressions, then the result is an algebraic of the form symb1 AND symb2. Execute →NUM (or set flag –3 before executing AND) to produce a numeric result from the algebraic result.

Access:	…ÃLLOGIC AND	(Ã is the rightshift of the 3key).
Flags:	Numerical Results (–3), Binary Integer Wordsize (–5 through –10)
