It was mentioned that 35s cannot proprely calculate cos (and some other trig functions) in certain ranges.
Where can I find examples with an appropriate argument and erroneous result given by 35s? I cannot seem to find the bad inputs.
Google finds numerous pages with a sentence "Cos(x) for x near 90 is dud". It also, surprisingly, finds this very thread.
However, what I am trying to find is actual numeric example of X where cos X is calculated incorrectly by 35s.
If found mentions of "cos(89.999) bug", but my 35s says
cos(89.999)=1.74532924306e-4 which agrees to 9 digits with what PC tells me. Is that a bug? That it is only 9 digits? Must be all 12?
