Calculator Question

[greatscott]

How many decimal places should I round to when inputing values/variables into calculator questions? Been doing 2 but I’ve noticed on some of answers, while close to the correct answer, are still far enough off to cause confusion on certain questions- particularily corp. fin. Does the CFAI recommend 3 or 4? Or what do you all find most helpful? TIA

If you’re using the TI, set the calculator to nine decimal places. It will automatically round it for you.
From there, common sense prevails on how to round the answer.
