>> ?

[lieip]

I'm trying to to translate a C hash function into VBA. But I'm a bit rusty on my C. What does << >> means? I thought it was only used in cin and cout.

Here:
h += (h<<10);

What does this << mean and how would I convert that to VBA?

TIA

Bit shift left -- multiply by 1024 (2 to the 10th).

 

[jstreich]

n<<x means shift the bits x times the left. Effectly creating a number that is 2 to the x power times bigger -- unless you run into overflow or your using signed integers.

n>>x means shift the bits x time to the right. Effectly deviding by 2 to the power x. Again, be aware that it shifts in zeros, so if you're using a signed int you can get odd results (negitive numbers become positive).
