On the HP30b, is it possible to enter non-integer P / YR values and thus not get an ERROR message? At HP, is there any way to convert decimal or fractional numbers to whole numbers (C / YR and P / YR)?

Currently, I find interest rates equivalent, either by a program on the HP30b, or by the traditional method. Is there a possibility to do this without a program?

Example: I have the rate 1.8% bimonthly (2 months) and I want the equivalent effective rate for quarter (3 months).

With the program I do:

1.8 I / YR 3 INPUT 2 ÷ N SHIFT PRGM =

Or manually:

1.8 I / YR PV = 1 N = 1 FV =? (= -1,0002) 2 INPUT 3 ÷ N I / YR =?

Answer: 2.7%

Sorry for the question and errors in English (I use Google Translate), but I'm starting on the HP30b. Still thanks and happy holidays!
