CJ1-H, CJ1M, and CS1D Only)
Example Programming
Sine Function (C: #0000)
The following example shows APR(069) used to calculate the sine of 30 .
(SIN(30) = 0.5000)
0.00
Cosine Function (C: #0001)
The following example shows APR(069) used to calculate the cosine of 30 .
(COS(30) = 0.8660)
0.00
Linear Extrapolation (C: Word Address)
• Using 16-bit Unsigned BCD or Binary Data
APR(069) processes
specified in S based on the control data in C
and the line-segment data specified in the
table beginning at C+1. The result is output
to D.
