G() (sum) G(Expr1, Var, Low, High) ⇒ ëG(Expr1, Var, High+1, LowN1) if High < LowN1 GInt( ) GInt(NPmt1, NPmt2, N, I, PV ,[Pmt], [FV], [PpY], [CpY], [PmtAt], [roundValue]) ⇒ value GInt(NPmt1,NPmt2,amortTable) ⇒ value Amortization function that calculates the sum of the interest during a specified range of payments. NPmt1 and NPmt2 define the start and end boundaries of the payment range. N, I, PV, Pmt, FV, PpY, CpY, and PmtAt are described in the table of TVM arguments, page 86. • If you omit Pmt, it defaults to Pmt=tvmPmt(N,I,PV,FV,PpY,CpY,PmtAt). • If you omit FV, it defaults to FV=0. • The defaults for PpY, CpY, and PmtAt are the same as for the TVM functions. roundValue specifies the number of decimal places for rounding. Default=2. GInt(NPmt1,NPmt2,amortTable) calculates the sum of the interest based on amortization table amortTable. The amortTable argument must be a matrix in the form described under amortTbl(), page 5. Note: See also GPrn(), below, and Bal(), page 10. Catalog > Catalog > 102 TI-Nspire™ Reference Guide
