C. System Flags

This appendix lists the calculator’s system flags. You can set, clear, and test all flags, although certain flags are used for specific purposes by the CAS and should not be altered. The default state of the flags is clear — except for flags –17, –27, –34, –90, –95 and –128 and the Binary Integer Math flags (flags –5 through –12).

	System Flags
Flag	Description
–1	Principal Solution.
	Clear: Symbolic commands return a result representing all possible solutions.
	Set: Symbolic commands return only the principal solution.
–2	Symbolic Constants.
	Clear: Symbolic constants (e, i, π, MAXR, and MINR) retain their symbolic form
	when evaluated, unless the Numerical Results flag –3 is set.
	Set: Symbolic constants evaluate to numbers, regardless of the state of the
	Numerical results flag –3.
–3	Numerical Results.
	Clear: Functions with symbolic arguments, including symbolic constants, evaluate
	to symbolic results.
	Set: Functions with symbolic arguments, including symbolic constants, evaluate to
	numbers.
–4	Not used. (Originally intended to control the careful evaluation mode in the
	HP 48SX, though it was never implemented.)
–5	Binary Integer Wordsize.
through	Combined states of flag –5 through –10 (the most significant bit) set the wordsize
–10	from 1 to 64 bits.
–11	Binary Integer Base.
and	HEX (default): –11 set, –12 set. DEC: –11 clear, –12 clear. OCT: –11 set, –12 clear.
–12	BIN: –11 clear, –12 set.
–13	Not used.
–14	Financial Payment Mode.
	Clear: TVM calculations assume endofperiod payments.
	Set: TVM calculations assume beginningofperiod payme nts.
–15	Coordinate System.
and	Rectangular: –16 clear.
–16	Polar/Cylindrical: –15 clear, –16 set.
	Polar/Spherical: –15 set, –16 set.
–17	Trigonometric Angle Mode.
and	Radians (default): –17 set.
–18	Degrees: –17 clear, –18 clear.
	Grads: –17 clear, –18 set.
–19	Vector/Complex.
	Clear: →V2 creates a 2dimensional vector from 2 real numbe rs.
	Set: →V2 creates a complex number from 2 real numbers.
