HP 17bII manual 170 12 The Equation Solver, HH.MMSS format, IFcond expr 1 expr, Svariable name

Table 12-2. Solver Functions for Equations (Continued)

Function	Description
HMS(time)	Converts time in decimal hours to
	HH.MMSS format.
HRS(time)	Converts time in HH.MMSS format to
IDIV(x:y)	decimal hours.
	Integer part of the quotient of x/y.
IF(cond:expr1:expr2)	Conditional expression: if cond is true, use
	expr1; if cond is false, use expr2. See page
	174.
INT(x)	Greatest integer less than or equal to x.
INV(x)	Inverse of x; 1/x.
IP(x)	Integer part of x.
ITEM(SUM-listname:item#)	Value of the specified SUM-list item.
L(x:expr)	Store the value of expr in the variable x.
	The variable will not appear in the SOLVE
	menu if it is only used in L and G functions.
	This is useful if you have a complex
	expression that uses the same sub
	expression multiples times for example:
	(1+i)^N x PV+((1–(1+i)^N)/(1–(1+i))) x PMT+FV
	It can be written: 
	
LN(x)	.
	Natural (base e) log of x.
LNP1(x)	In (1 + x)
LOG(x)	Common (base 10) log of x.
MAX(x:y)	Compares x and y, and returns the larger
	of the two.
MIN(x:y)	Compares x and y, and returns the smaller
	of the two.
MOD(x:y)	Remainder of the division x/y. MOD(x,y) =
	x－y x INT(x/y)
PI	π ; 3.14159265359 (12 digits).
RND(x:y)	Rounds x to y decimal places if 0 ≤ y ≤ 11,
	or rounds x to y significant digits if －12 ≤
	y ≤－1. y must be an integer.
S(variable name)	Used in an IF function to test if solving for
	the variable named. Used to combine
	related equations into one Solver menu.
	See page 178.
SGN(x)	Sign of x (＋1 if x>0, 0 if x＝0,－1 if x<0.
