NullableDouble

Remarks

The equal and not equal operations are actually internal and external range tests based on the setpoint and the tolerance. The two tests are performed as follows.

Equal: (value >= SetPoint - Tolerance) && (value <= SetPoint + Tolerance)
Not equal: (value < SetPoint - Tolerance) || (value > SetPoint + Tolerance)
