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) "我们刚才说过,C 有四种数据类型,分别...

The default implementation is capable of decoding * the specified region into an unsigned 8/16/24/32/64 bit integer. Override this method to decode the length field encoded * differently. Note that this method must not modify the state of the specified buffer (e.g. {@code readerIndex}, ...
return int The integer value of var on success, or 0 on failure. Empty arrays and objects return 0, non-empty arrays and objects return 1. The maximum value depends on the system. 32 bit systems have a maximum signed integer range of -2147483648 to 2147483647. So for example on such a...
If you are building for 64 bit code a size_t is a 64 bit value. So if you pass a size_t to a function that takes a 32 bit value as a parameter (i.e., int or unsigned int) then the size_t parameter would be truncated to 32 bits. The compiler is warning about this ...

为了更简单的知道NSInteger和long的大小,我们只需要记住它们的大小总是等于指针的大小,即在32bit系统中是32bit,在64bit系统大小总是64bit。(NSInteger and long are always pointer-sized. That means they're 32-bits on 32-bit systems, and 64 bits on 64-bit systems.) ...
For example, when converting a 16-bit signed integer to an eight-bit signed integer, if the 16-bit value is in the range -128..+127 you simply copy the L.O. byte of the 16-bit object to the eight-bit object. If the 16-bit signed value is greater than +127, then you clip ...
