G Prn(pmt1,pmt2 [ ,roundvalue ] )
G Int( computes the sum of the interest during a specified period for an amortization
schedule using stored values for
¾æ,
PV , and PMT . pmt1 is the starting payment. pmt2 is
the ending payment in the range. pmt1 and pmt2 must be positive integers < 10,000.
roundvalue specifies the internal precision the calculator uses to calculate the interest; if
you do not specify roundvalue , the TI-84 Plus uses the current Float/Fix decimal-mode
setting.
