WebJul 15, 2024 · If you shift on left (multiply by 2) a signed number 0101 (5) you are going to overflow producing 10 unsigned but 1010 which is -6 since it will wrap around. On top of that the << operator is a logical operator the arithmetic one which will take care of signed operands is <<<. WebDec 4, 2016 · An video buffer may be adaptive in size with presets for single, double or triple buffering on video frames, an audio buffer may be different again, giving more circular buffers more flexibility and complexity, such as using virtual memory with multiple integer sized mapped buffers.
