Function
(1) The unit expressing the size of an angle is converted into the degree unit from the radian unit specified by , and its
result is stored into the device specified by .
(2) The conversion from radians to angles is performed according to the following equation:
(3) When the operation results in -0 or an underflow, the result is processed as 0.
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.
Program Example
(1) The following program converts the radian value set with 64-bit floating decimal point type real number at D20 to D23 to
angles, and stores the result as a BCD value at Y40 to Y4F.
