Warning W1024 Rising When Combining Signed and Unsigned Types in UpdateCrc32 Function #11
Description
The UpdateCrc32 function is generating warning W1024, indicating a combination of signed and unsigned types, resulting in an implicit widening of both operands. This can lead to undesirable or unexpected behavior. The function is:
function UpdateCrc32(Value: Byte; Crc32: Cardinal): Cardinal;
begin
Result := (Crc32 shr 8)
xor crc32tab[Byte(Value xor (Crc32 and Integer($000000FF)))];
end;To resolve this warning, I made this adjustment, and the warning stopped appearing:
Result := (Crc32 shr 8)
xor Cardinal(Crc32Tab[Byte(Value xor (Crc32 and Integer($000000FF)))]);
