at increments of s.
See page 176.
SIZEC(CFLO-listname) The number of the last flow in specified
CFLO list.
SIZES(SUM-listname) The number of items in specified SUM
list.
SPFV(i%:n) Future value of a single $1.00 payment;
equivalent to (1 + i%
÷ 100) n . n is the
number of compounding periods. i% is
the interest rate per compounding
period, expressed as a percentage.
SPPV(i%:n) Present value of a single $1.00
payment; equivalent to 1
÷ SPFV(i%:n).
n is the number of compounding
periods. i% is the interest rate per
compounding period, expressed as a
percentage.
SQ(x) Square of x ; x 2 .
SQRT(x) Square root of x ; X .
#T( CFLO-listname:flow#) The number of times that specified cash
flow occurs.
TRN( x:y) Truncates x to y decimal places if 0 ≤ y
≤11, or truncates x to y significant digits
if
－12 ≤ y ≤－1. y must be an integer.
USFV( i%:n) Future value of a uniform series of
$1.00 payments; equivalent to
(SPFV(
i%:n)－1) ÷ (i% ÷100). n is
number of payments. i% is periodic
interest rate, expressed as a
percentage.
USPV( i%:n) Present value of a uniform series of
$1.00 payments; equivalent to
USFV(
i%:n) ÷ SPFV(i%:n). n is number of
payments. i% is periodic interest rate,
expressed as a percentage.
