The actual result for SIN(90 ° ) and COS(0 ° ) is 1, but 9999 (0.9999) will be out-
put to R.
An error will occur if C is a constant greater than 0001.
An error will occur if linear extrapolation is specified but the X coordinates are
not in ascending order (X
An error will occur if linear extrapolation is specified and BCD input is speci-
fied (bit 15 of C ON) but S is not BCD.
An error will occur if a trigonometric function is specified (C=0000 or 0001) but
S is not BCD between 0000 and 0900.
