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.
