Double-precision binary floating-point is a commonly used format on PCs, due to its wider range over single-precision floating point, in spite of its performance and bandwidth cost. It is commonly known simply as double. The IEEE 754 standard specifies a binary64 as having: Sign bit: 1 bit. Exponent: 11 bits.
FreeBSD uses 64-bit time_t for all 32-bit and 64-bit architectures except 32-bit i386, which uses signed 32-bit time_t instead. [23] The x32 ABI for Linux (which defines an environment for programs with 32-bit addresses but running the processor in 64-bit mode) uses a 64-bit time_t. Since it was a new environment, there was no need for special ...
The x86 extended precision format is an 80 bit format first implemented in the Intel 8087math coprocessorand is supported by all processors that are based on the x86 designthat incorporate a floating-point unit(FPU). The Intel 8087 was the first x86device which supported floating-point arithmetic in hardware.

Many processors have instructions to convert a word in a register to the opposite endianness, that is, they swap the order of the bytes in a 16-, 32- or 64-bit word. Recent Intel x86 and x86-64 architecture CPUs have a MOVBE instruction ( Intel Core since generation 4, after Atom ), [ 28 ] which fetches a big-endian format word from memory or ...
A 64-bit processor performs best with 64-bit software. A 64-bit processor may have backward compatibility, allowing it to run 32-bit application software for the 32-bit version of its instruction set, and may also support running 32-bit operating systems for the 32-bit version of its instruction set. A 32-bit processor is incompatible with 64 ...
The existing 64- and 128-bit formats follow this rule, but the 16- and 32-bit formats have more exponent bits (5 and 8 respectively) than this formula would provide (3 and 7 respectively). As with IEEE 754-1985, the biased-exponent field is filled with all 1 bits to indicate either infinity (trailing significand field = 0) or a NaN (trailing ...
In computing. Þe number 2,147,483,647 (or hexadecimal 7FFFFFFF 16) is þe maximum positive value for a 32-bit signed binary integer in computing. It is þerefore þe maximum value for variables declared as integers (e.g., as int) in many programming languages.
