Note that we must ensure that the upper 32 bits of the 64-bit registers are zero, so that any leftover values in bit 32 don’t infect the sum. The instructions to zero out the upper 32 bits may be elided if you know ahead of time that they are already zero. This is common on x...
aAs usual, Name is a descriptive name for the Tx_Port element. 照常,名字是一个描写名字对于Tx_Port元素。 [translate] aThe Port_ID is a 32-bit unsigned integer that “identifies” the transmit port. Port_ID是“辨认”传送口岸的32位无符号整型。 [translate] ...
1).计算机最小的存储单位是“位” 也就是bit或binary digits,用来存放一个二进制数,即 0或1。 8个二进制位为一个字节Byte。 2).对于 16-bit(16位)的计算机,int是以两个字节来储存的,而32-bit的计算机,则是以4个字节,即32个bit来储存的。 如果想要明白singed与unsigned的区别,除了这两个基本知识,还需要...

The MQULONG data type is a 32-bit unsigned binary integer that can take any value in the range 0 through +4 294 967 294, unless otherwise restricted by the context. An MQULONG must be aligned on a 4-byte boundary. Parent topic: Elementary data types ...

where the sign makes no sense, and/or where we'd rather have a larger possible range of positive values than the possibility of negative numbers: such as a memory location or file size. When an integer is signed, one of its bits becomes the sign bit, meaning that the maximum magnitude ...
Fortran doesn't have an unsigned integer type. Depending on your needs, as Tim suggests, the integer*8 type can hold the full range of a 32-bit unsigned. Some might suggest relying on integer overflow checking being off to do "unsigned arithmetic, but that's risky as the compiler makes ...
