Interpolation in Black scholes pricing model

Eemad10y ago
John, Do we need to interpolate (in case of 3 or 4 decimal places) to calculate an exact amount for d1 & d2 in black scholes? In most of the answers given in approved revision kits, it seems to be a normal practice and seems to be required. I was wondering if i take only 2 decimal places and go with the distribution table i might not score full.

The approved revision kits do it because their answers are simply copied from the examiners own answers, and he does it :-) If you have the time, then do interpolate. However I myself would not bother in the exam - you will not lose marks (unless maybe you were otherwise getting 100% - then they might subtract a mark :-) )
