This is apparently a difference in behavior between browsers that has nothing
to do with CryptoJS.
parseInt('FF4B247BC9C50193E1C8074003D1C3D0', 16)
You're trying to get a 64-bit number from a 128-bit value, and apparently the
browsers do that slightly differently.

I've researched the issue. Not CryptoJS. IE arithmetic with very long numbers
is different from other browsers. It is less accurate in the last digit of
precision.
