Function
(1) The unit expressing the size of an angle is converted into the radian unit from the degree
unit specified by
(2) Conversion from degree to radian units 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.
