August 16, 2015 How to convert a ubyte to a byte without losing information? | ||||
---|---|---|---|---|

I can cast a ubyte to a byte, but as far as I know I'd only get positive values out of that conversion. If I was instead getting a ubyte out of a function and I want to assign those bits to a byte and have some of those numbers be interpreted as negative values by the new type they're in, how would I cast that in D? |

ubyte b = 255;
byte b2 = cast(byte) b;
assert(b2 == -1);
No information is lost by that cast, all the bits remain exactly the same.
