In the following example, the BCD contents of the 8 words from DM 0000 to
DM 0007 are added when IR 00001 is ON and the result is written to DM
0010 and DM 0011.

For trigonometric functions S must be BCD from 0000 to 0900 (0 °≤ θ ≤ 90 ° ).
DM 6144 to DM 6655 cannot be used for D.
When the execution condition is OFF, APR(––) is not executed. When the exe-
cution condition is ON, the operation of APR(––) depends on the control word
C.
If C is #0000 or #0001, APR(––) computes sin( θ ) or cos( θ )*. The BCD value of
S specifies θ in tenths of degrees.
If C is an address, APR(––) computes f(x) of the function entered in advance
beginning at word C. The function is a series of line segments (which can
approximate a curve) determined by the operator. The BCD or hexadecimal
value of S specifies x.
ER: Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
For trigonometric functions, x > 0900. (x is the content of S.)
A constant other than #0000 or #0001 was designated for C.
The linear approximation data is not readable.
EQ: The result is 0000.
