Function
Calculates the cosine, or sine of the given
degree value, or determines the y-coordi-
nate of the given x value in a previously es-
tablished line graph. For the sine and co-
sine conversions, S is entered in BCD as
an angle (in the range 0.0 to 90.0 degrees).
When calculating the y-coordinate in a
graph, S gives the address of the value of
the x-coordinate. The calculated data is
transferred to the destination word (D).
Sine and cosine results are given in BCD.
Line graph coordinate calculations (inter-
polation) can be in BCD or BIN.
The data in the control word (C) deter-
mines which operation is performed. If C is
entered as a constant with a value of 0000
or 0001, the sine or cosine, respectively, of
the source data value is calculated. If C is
entered as a word designation, it gives the
address of the first word of the data table
for the line graph. The value of the first two
digits gives m–1, where m is the number of
data points for which coordinates are given
on the line graph. Bits 14 and 15, respec-
tively, specify the output and input data for-
mats (0 indicates BCD, 1 indicates binary).
