HP 30b programs Interest Rate conversions Negative Periods per Year and Fractional Periods per year Message #1 Posted by gene wright on 2 May 2011, 2:53 p.m. These programs allow the use of negative values for "Periods per year" when converting interest rates. They also allow the use of fractional periods per year. End of period compounding assumed. First program: Computing the effective rate. Inputs: Nominal rate, =, number of periods. / Ans ) Swap 1 + ) Swap Y^X 1 - Shift+Stop When run from the program catalog, key 0.1224 = 2 +/- = = Result shown is 0.1346 2nd program: Effective rate to nominal rate. Inputs: Effective rate, =, number of periods. = = shift+UP 1 + ) Swap 1/x Y^X 1 - * Shift+STOP Inputs: 0.1346 = 2 +/- = = Outputs 0.1224 Inputs: 0.1346 = 360 = 210 / = Outputs: 0.1310 Edited: 2 May 2011, 3:15 p.m.
