Bit-Shifting

[Orpheus]

Does anybody have any routines for emulating a left-shift on a number as per the C "<<" operator.

I think I have successfully replicated the right-shift but do not seem to be abe to get the left shift working properly.

Do you mean bit-shifting for numbers (x/2) or strings(rotl and rotr in asm?)?

[Orpheus]

Numbers
ie: SHL/SHR

[oetje]

Can't you do something like this?

Dim Number As Double

Number = 1000

'bit shift?
Number = Number / 2

This does not always replicate the functions correctly and therefore does not alays return the correct value.
