Table 12-2. Solver Functions for Equations

Function	Description

ABS(x)	Absolute value of x.
ALOG(x)	Common (base 10) antilogarithm;
	10x.
CDATE	Current date.
CTIME	Current time.
DATE(d1:n)	The date n days after (when n is
	positive) or before (when n is
	negative) date d1. The format for d1
	is set in the TIME/SET menu.
DDAYS(d1:d2:cal)	Number of days between dates d1
	and d2. Formats for d1 and d2 are
	set in the TIME menu; cal designates
	the calendar:
	cal ＝ 1 for the actual calendar,
	which recognizes leap years.
	cal ＝ 2 for the 365-day
	calendar, which ignores leap
	years.
	cal ＝ 3 for the 360-day
	calendar, which uses 12, 30-day
	months.
EXP(x)	Natural antilogarithm; ex.
EXPM1(x)	ex－1.
FACT(x)	x!; factorial of a positive integer.
FLOW(CFLO-listname:flow#)	Value of the specified cash flow.
FP(x)	Fractional part of x.
G(x)	Returns (Get) the value of the variable.
	The variable will not appear in the
	SOLVE menu if it is only used in L and
	G functions. See L function on page
	170.
