G Prn(, G Int(
G Prn( computes the sum of the principal during a specified period for an
amortization schedule using stored values for æ , 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 principal; if you do not specify
roundvalue , the TI-83 Plus uses the current Float / Fix decimal-mode setting.
Note: You must enter values for æ ,
PV
,
PMT
, and before computing the
principal.
