How many bits in a bigint
WebFeb 28, 2024 · 简介. Java 内置的整数类型 int 为32 bit. 它可以表示的整数范围为 $-2^ {31}$ 到 $2^ {31}-1$ (约40亿个数). 这些整数足够应对普通的任务. 但一些特殊任务, 可能需要能够支持更大范围的整数. 例如在加密算法 (如 RSA )中, 往往需要用到很大的素数. 素数越大, 加密算法 … WebFirst off, the top bit of an integer (bit 32 in an INT) is different in that it represents the sign bit. Our function can’t easily deal with this because it doesn’t know what sort of integer (Int, smallint or tinyint) you’ve passed to it, so it determines the smallest integer that can accommodate the value.
