Method Detail

intValue

public int intValue()

Return the value of this AutoMedInteger as an int

longValue

public long longValue()

Return the value of this AutoMedInteger as an long

doubleValue

public double doubleValue()

Return the value of this AutoMedInteger as a double

Specified by:

doubleValue in class AutoMedType

add

public AutoMedInteger add(AutoMedInteger v)

Return the sum of two AutoMedIntegers.
