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.}
