-.TH __SETFPUCW 3 2012-12-31 "Linux" "Linux Programmer's Manual"
-.SH NAME
-__setfpucw \- set FPU control word on i386 architecture (obsolete)
-.SH SYNOPSIS
-.B #include <i386/fpu_control.h>
-.sp
-.BI "void __setfpucw(unsigned short " control_word );
-.SH DESCRIPTION
-.BR __setfpucw ()
-transfers
-.I control_word
-to the registers of the FPU (floating-point unit) on the i386 architecture.
-This was used to control floating-point precision,
-rounding and floating-point exceptions.
-.SH CONFORMING TO
-This function was a nonstandard GNU extension.
-.SH NOTES
-As of glibc 2.1 this function does not exist anymore.
-There are new functions from C99, with prototypes in
-.IR <fenv.h> ,
-to control FPU rounding modes, like
-.BR fegetround (3),
-.BR fesetround (3),
-and the floating-point environment, like
-.BR fegetenv (3),
-.BR feholdexcept (3),
-.BR fesetenv (3),
-.BR feupdateenv (3),
-and FPU exception handling, like
-.BR feclearexcept (3),
-.BR fegetexceptflag (3),
-.BR feraiseexcept (3),
-.BR fesetexceptflag (3),
-and
-.BR fetestexcept (3).
-.PP
-If direct access to the FPU control word is still needed, the
-.B _FPU_GETCW
-and
-.B _FPU_SETCW
-macros from
-.I <fpu_control.h>
-can be used.
-.SH EXAMPLE
-.B __setfpucw(0x1372)
-
-Set FPU control word on the i386 architecture to
-.br
-     \- extended precision
-.br
-     \- rounding to nearest
-.br
-     \- exceptions on overflow, zero divide and NaN
