Calculator Decimal Places

Just curious, how many decimal places do you set your calculator to? I know it does not make a material impact but just wondering if everyone prefers to round on their own and use 9 decimals or if you prefer your calculator to do the work for you at 4 decimals.

I use five. 4 can get you into trouble.

¯\_(ツ)_/¯ It be like that sometimes.

Five here, although I doubt anything above three will matter much on level II. You do need the 5 digits for level one as far as I recall from personal experience.

Checked mine and I have 6, my lucky number is 7 so I wanted to see 7 sig figs when I clear everything. Either that or it came like that stock and I can’t think of a better reason.

We’re gonna win so much, you may even get tired of winning. And you’ll say, 'Please, please. It’s too much winning. We can’t take it anymore. Mr. President, it’s too much.' And I’ll say, 'No, it isn’t!' We have to keep winning!

good luck calculating triangular arbitrage! 

It ain't what you don't know that gets you in trouble. It's what you know for sure that just ain't so.

To be fair, i don’t remember there being much difference on decimal places, even more is the convention between 360 / 365 and since level 1 and 2 are all multiple choices, you end up selecting the ‘closest’ choice regardless. Maybe my memory is vague on it….

My brain* skipped it. Haven’t even taken the exam and I clearly forgot a chunk of Economics ever happened (and perhaps derivatives as well as a little of fixed income (spot/par/forward rates), now that I think about it) requires a higher degree of precision. Whoopsies. Thank you for pointing that out!

Bring two calculators and set it to 18. Precision is paramount.

Got a AM mock question on currency forwards wrong today because the solutions carried 6dp and my calc had 5dp. I might get partial credit if they’re generous, but not risking it..
