MgDataPropertyDefinition::Length ,GetLength() and SetLength() can be assigned to with a negative value;

1. Construct an instance of MgDataPropertyDefinition using the following code
   

MgDataPropertyDefinition dataPropDefinition = new MgDataPropertyDefinition("dataPropDefinition");

2. Assigned a negative value to Length and use method GetLength to return the value
   

dataPropDefinition.Length = -10; Assert.AreEqual(-10, dataPropDefinition.GetLength());

3. Use the method SetLength to set a negative value, and use Length to return the value
   

dataPropDefinition.SetLength(-23);

Assert.AreEqual(-23, dataPropDefinition.Length);

Sample code:

MgDataPropertyDefinition dataPropDefinition = new MgDataPropertyDefinition("dataPropDefinition");

dataPropDefinition.Length = -10;

Assert.AreEqual(-10, dataPropDefinition.Length);

Assert.AreEqual(-10, dataPropDefinition.GetLength());

dataPropDefinition.SetLength(-23);

Assert.AreEqual(-23 dataPropDefinition.Length);

Assert.AreEqual(-23, dataPropDefinition.GetLength());

Scale property can have negative values. When scale is negative, it means that the values must be mulitples of 10^{-(scale), i.e. when scale = -2, values must be multiples of 100. Refer to FDO external id 1038260.01.}
