754 (foldoc) | IEEE Floating Point Standard
754
IEC 559
IEEE 754
(IEEE 754) "IEEE Standard for Binary
Floating-Point Arithmetic (ANSI/IEEE Std 754-1985)" or IEC
559: "Binary floating-point arithmetic for microprocessor
systems". A standard, used by many CPUs and FPUs, which
defines formats for representing floating-point numbers;
representations of special values (e.g. infinity, very small
values, NaN); five exceptions, when they occur, and what
happens when they do occur; four rounding modes; and a set
of floating-point operations that will work identically on any
conforming system.
IEEE 754 specifies formats for representing floating-point
values: single-precision (32-bit) is required,
double-precision (64-bit) is optional. The standard also
mentions that some implementations may include single-extended
precision (80-bit) and double-extended precision (128-bit)
formats.

p1754 (foldoc) | P1754
IEEE Std 1754-1994 "A 32-Bit
Microprocessor Architecture". The IEEE standard defining a
version of the SPARC microprocessor architecture.
The P1754 standard (the first microprocessor standard) was
approved after four years on 1994-03-17. It is compatible
with, but distinct from, SPARC International's 32 bit
version of the SPARC Architecture, SPARC V8, from which it is
largely derived. It is possible for a processor to comply
with neither, one, or both specifications.
