How to "Zero-fill right shift" ?

Hi,
I'm wondering how to make a zero-fill right shift in autoit as far as the BitShift function has no parameter for this.

Here is an example in javascript : https://developer.mozilla.org/en-US/docs/Javascript/Reference/Operators/Bitwise_Operators#>>>_(Zero-fill_right_shift)

Thanks for anyhelp,

Br, FireFox.
