Hi Darshan,
I like to start with the exponent
.05 x 1 +-/ = -.05
2nd LN (display: 0.851229)
x 80 = 76.098
or if you like parens, could go left to right:
80 x (.05 +/- x 1) 2nd LN = 76.098
Please not LN() and EXP() are inverse functions, so, for example, LN(EXP(5%) = 5%
....and they share the same key, so 2nd LN gives you the e^

sure thing...differences are likely due to settings, so it's good to have the calculator set. Looks like you have the decimals set to 2.0.
Please try
2nd
(.) ;i.e., FORMAT
4
enter key
now your display should be 4 decimals

i think so, at least. 5 or 6 is okay too (easier to round off then go the other way). to me, 4 is a minimum b/c that gets you to 1 basis point (x.xx%). David
Hi David,
Isn't it easy to use the exponential function than LN unless I did not understand whay you specifically used LN function.
80e^-0.05*1
first calculate the expont: -.05 * 1 = -.05
keep the answer and press second e^x function key, thus you get the discount factor 0.951229
keep same answer and multiply by 80 to get 76.098354.
Thanks.

Hi Dinesh,
Agreed, the LN is just to reference the same key; "they share the same key, so 2nd LN gives you the e^" ... on both my TI BA II+ and TI BA II+ pro the exponential function shares the LN() key, so i was just trying to explain where EXP can be found...but i agree with you, I think you must use the exp function to get the answer...David
