public final class AddConverter extends UnitConverter
This class represents a converter adding a constant offset
(approximated as a double) to numeric values.
Instances of this class are immutable.

For linear converters the following property always hold:[code]
y1 = c1.convert(x1);
y2 = c2.convert(x2);
then y1*y2 = c1.concatenate(c2).convert(x1*x2)[/code]isLinear in class UnitConvertertrue if this converter is linear;

UnitConverterNote: Implementations must ensure that the UnitConverter.IDENTITY instance
is returned if the resulting converter is an identity
converter.
