WebDec 26, 2024 · The maximum (unsigned) 64-bit integer is 18446744073709551615. This is (2^64)-1, which is essentially the square of (2^32)-1, which is "about" 4 billion. In general, you can estimate that every 10 bits represents 3 decimal digits. For 64 bits, that means a good estimate would be 16 (from the 4 leftover bits) followed by 18 zeroes (6*3). Webx86 具有在有符號整數和浮點數之間轉換的指令。 AVX512（我認為）支持無符號整數轉換，大多數編譯器默認情況下不假設。 如果將uint64_t右移一次，符號位就消失了，因此您可以將其解釋為有符號整數並得到相同的結果。 WebDec 5, 2009 · 6.
