[Closed] bit.shift question

May 17, 2007 6:42 pm

Hi,

I need to import data from a binary file. (a 3D object with custom properties)

I have a question regarding the bit.shift mehod:

bit.shift val amount
if amount is a positive integer, then a left shift is performed
if amount is a negative integer, then a right shift is performed

so far, so good

but I need to do a ‘zero fill right shift’
I am at lost here, could anyone help me out please ?

Thanks in advance for any clues

Here is a workaround mentioned:

Apparently, a >>> b is equal to the following:

    if a >= 0: return a >> b
    else: return (a>>b)+(2<<~b)
