Floating-point Data
Sample program
Sine Function (C: #0000)
The following example shows APR(069) used to calculate the sine of 30°.
(SIN(30) = 0.5000)
0.00
#0000
Cosine Function (C: #0001)
The following example shows APR(069) used to calculate the cosine of 30°.
(COS(30) = 0.8660)

Linear Extrapolation (C: Word Address)
• Using 16-bit Unsigned BCD or Binary Data
APR(069) processes the input data speci-
fied 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.
