7.9 Real Number Instructions
Processing details
• These instructions calculate the angle based on the tangent data in the device specified by (s), and store the operation
result in the device number specified by (d).
• The angle (operation result) is stored in radians in the device specified by (d).
• If the operation result is -0 or an underflow occurs, the operation result turns out to 0.
• When an input value is set using the engineering tool, a rounding error may occur. Refer to the following for the precautions
on setting input values using the engineering tool.
