    Method
    Description
    final void
    constructorTest()
    See if we can increase the code coverage to include the private constructor.
    static String
    convertAndVerify(double val, int room)
    Call convert and then verify that the result is an accurate representation of the value.
    final void
    doULPTest()
    Test cleverly chosen values plus and minus one ULP.
    final void
    doWidthTest()
    Check that values are formatted at optimal precision when the room is varied.
    static void
    testD(double d, int width)
    Print result of main value and value plus or minus one ULP.
    final void
    ulpTest()
    Run ulpTest with both values of the parameter.
    static void
    verifyResult(double value, String text, int room)
    Check that a double value is represented by a string as accurately as possible; i.e. the last digit in the mantissa is rounded correctly.
    final void
    widthTest()
    Run widthTest with both values of the parameter.
