From: http://www.network-theory.co.uk/docs/gccintro/gccintro_70.html
The IEEE-754 standard defines the bit-level behavior of floating-point arithmetic operations on all modern processors. This allows numerical programs to be ported between different platforms with identical results, in principle. In practice, there are often minor variations caused by differences in the order of operations (depending on the compiler and optimization level) but these are generally not significant.
However, more noticeable discrepancies can be seen when porting numerical programs between x86 systems and other platforms, because the the x87 floating point unit (FPU) on x86 processors computes results using extended precision internally (the values being converted to double precision only when they are stored to memory). In contrast, processors such as SPARC, PA-RISC, Alpha, MIPS and POWER/PowerPC work with native double-precision values throughout. The differences between these implementations lead to changes in rounding and underflow/overflow behavior, because intermediate values have a greater relative precision and exponent range when computed in extended precision. In particular, comparisons involving extended precision values may fail where the equivalent double precision values would compare equal.
To avoid these incompatibilities, the x87 FPU also offers a hardware double-precision rounding mode. In this mode the results of each extended-precision floating-point operation are rounded to double precision in the floating-point registers by the FPU. It is important to note that the rounding only affects the precision, not the exponent range, so the result is a hybrid double-precision format with an extended range of exponents.
On BSD systems such as FreeBSD, NetBSD and OpenBSD, the hardware double-precision rounding mode is the default, giving the greatest compatibility with native double precision platforms. On x86 GNU/Linux systems the default mode is extended precision (with the aim of providing increased accuracy). To enable the double-precision rounding mode it is necessary to override the default setting on per-process basis using the FLDCW "floating-point load control-word" machine instruction, which will be performed by this method.
