Class ExpConverter

java.lang.Object

tec.uom.se.AbstractConverter

tec.uom.se.function.ExpConverter

All Implemented Interfaces:

Serializable, javax.measure.UnitConverter, tec.uom.lib.common.function.ValueSupplier<String>, Converter<Number,Number>

public final class ExpConverter
extends AbstractConverter
implements tec.uom.lib.common.function.ValueSupplier<String>

This class represents a exponential converter of limited precision. Such converter is used to create inverse of logarithmic unit.

This class is package private, instances are created using the LogConverter.inverse() method.
