7.9 Real Number Instructions

Processing details

• These instructions calculate the logarithm using natural logarithm (e) of the value specified by (s), and store the operation

result in the device specified by (d).

• Input a positive value only. (No negative value can be calculated.)

• 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.
