 .SH NAME
-__setfpucw \- set fpu control word on i386 architecture (obsolete)
+__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 );
-.br
+.PP
+.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 i386 architecture. This 
-was used to control floating point precision, rounding and floating point 
-exceptions.
+.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.

      \- rounding to nearest
