RADD(P)
7.12.14 Conversion from floating-point angle to radian
(Double precision) (RADD(P))
RADD(P)
Function
(1) The unit expressing the size of an angle is converted into the radian unit from the degree
unit specified by , and its result is stored into the device 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.
• The value of the specified device is not in the following range: (Error code: 4140)
