operations (BATAN(P))
BATAN(P)
Function
(1) Performs TAN
-1
(inverse tangent) on value designated by and stores operation results
(angles) at device designated by .
(2) A sign for the operation data is set at .
If the operation data is a positive value, this is set at "0", and if it is a negative value, it is set
at "1".
(3) The part before the decimal point and fraction part are stored at +1 and +2 respectively,
as BCD values.
(Values from 0 to 9999.9999 can be set.)
(4) Operation results stored at are BCD values between 0 and 90 degrees, and 270 and 360
degrees (degree units).
(5) Calculation results are a value from which the decimal fraction part has been rounded.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• The operation data designated by is not a BCD value. (Error code: 4100)
• The device specified by exceeds the range of the corresponding device.
(For the Universal model QCPU, LCPU.) (Error code: 4101)
: Number of the device where data of which the TAN-1 (inverse tangent) value is obtained is stored
(BCD 4 digits)
: Head number of the devices where the operation result will be stored (BCD 4 digits)
