+Summary: interop problem with serialization and deserialization of float and double
|
|
+
|
|
+Description of Problem:
|
|
+when trying to serialize the objects "double.MaxValue"
|
|
+and "float.MaxValue" the serialization writes it in precision of 15 in
|
|
+case of double and precision 7 in case of float, which is the default,
|
|
+while the .NET framework writes these values in precision of 17 and 9.
|
|
+This cause the deserialization loose information and the deserialized
|
|
+object to be different than the serialized one.
|
|
+
|
|
+Steps to reproduce the problem:
|
|
+1. serialize double.MaxValue to a file
|
|
+2. deserialize the object.
|
|
+3. compare the serialized object to the deserialized one using equals
|
|
+4. repeat stages 1-3 for float.MaxValue
|
|
+
|
|
+Actual Results:
|
|
+ comparing these objects using equals results in false
|
|
+
|
|
+Expected Results:
|
|
+ the values should be equals
|
|
+
|
|
+How often does this happen?
|
|
+ every time.
