This bit representation corresponds to-1forintandUINT_MAXforunsignedint. Thus, if the result has typeint, a signed comparison is used and the less-than test is true; if the result has typeunsignedint, an unsigned comparison is used and the less-than test is false. The addition of a cast...
Hence, the 16-bit unsigned integer has the range 0−65535 (216 − 1) and the 32 bit 0−4294967295 (232 − 1). There is also a 1-bit type for bit storage. Table 2.2. Range of Integer Variables NameTypeMinimumMaximumRange int1 1 bit 0 1 1 = 20 unsigned int8 8 bits 0 ...

A conversion between signed and unsigned types of the same with to each other is done by reinterpreting the bit pattern of a number as signed or unsigned. ThereforeUInt.MAX_VALUE.toInt()will turn into-1. signed/unsigned narrowing conversion ...
符号位(sign bit):最高位是 0 表示正数,最高位是 1 则表示负数。 这里我们可以看到 -10 的最高位是 1,这个 1 就是符号位了,表示它是一个负数。 ②原码的符号位不变,其它位一律按位取反,即为反码。 ③反码 +1,得到的就是补码。 Ⅱ. 整数类型(Integer Types) ...
