Peniel,the task was "2 decimal places", so 14n.abcd... will do (except you are asked to obey certain rounding rules).And - of course - "any trained mathematician knows that", but without uppish attitude: search for the magicword 'range reduction', the recipe is to reduce to x close to 0 (though it practically not relevant in commonprecision and covered by the HW implementation). That's what I wrote down first (the usual variant is to useapproximations towards 0 instead of alternating series, since that for fixed precision is faster).But I think the only point is range reduction (and rounding rule).
