I started using Julia yesterday. My objective to rewrite a data-analysis program written in Python that currently takes more than 24 hours, and cut it down to a few hours.
The first hurdle is the following. From a bitstring (>300bit) I isolate 8-bit in an Int64 variable. The problem is that my 8-bit represents a signed integer. How do I get from the 8-bits in Int64 to Int8 (-128, 127) elegantly and fast? Right now the result ranges (0, 255).
Thanks for any suggestion
