* Complex numbers can be used as arguments.
• Precision is basically the same as that described under

x
• x , y , x! , n P r , n C r type functions require consecutive internal calculation, which can cause accumulation of
errors that occur with each calculation.
• Error is cumulative and tends to be large in the vicinity of a function's singular point and inflection point.
