 Conversion from degree units to radian units is performed using the following equation:
Radian units = Degree units × π / 180
 When the operation results in "-0" or an underflow occurs, the operation result is processed as "0".
 When setting input values from programming tools, rounding errors may occur.
For precautions when setting input values from programming tools, refer to "6.3.4 Single/Double-Precision Real Number
