Function
The Zone instruction controls the value of data to control In according to the positive bias, BiasP, and
the negative bias, BiasN. The value of processing result Out is as shown below.
Value of In
In < 0
In = 0
0 < In
The following example is for when BiasP is INT#20 and BiasN is INT#−20.

Precautions for Correct Use
• In, BiasP, BiasN, and Out may be different data types, but observe the following precaution.
• Set the valid range of Out to include the valid ranges of In, BiasP, and BiasN.
• If the value of In is nonnumeric data, the value of Out is nonnumeric data.
• If the value of In, BiasP, or BiasN is positive infinity or negative infinity, the value of Out is as shown
below.
