• Sine Function (C=0000)
When C is 0000, APR(069) calculates the SIN(S) and writes
the result to R. The range for S is 0000 to 0900 BCD (0.0° to
90.0
°) and the range for R is 0000 to 9999 BCD (0.0000 to
0.9999). The remainder of the result beyond the fourth deci-
mal place is eliminated.
• Cosine Function (C=0001)
When C is 0001, APR(069) calculates the COS(S) and writes
the result to R. The range for S is 0000 to 0900 BCD (0.0
° to
90.0
°) and the range for R is 0000 to 9999 BCD (0.0000 to
0.9999). The remainder of the result beyond the fourth deci-
mal place is eliminated.
Note The actual result for SIN(90
°) and COS(0°) is 1, but 9999 (0.9999) will be output to R.
