+.SH NAME
+fetestexcept \- test floating-point exception flags
+.SH SYNOPSIS
+.LP
+.nf
+c99 [ \fIflag\fR... ] \fIfile\fR... \fB-lm\fR [ \fIlibrary\fR... ]
+#include <fenv.h>
+
+\fBint\fR \fBfetestexcept\fR(\fBint\fR \fIexcepts\fR);
+.fi
+
+.SH DESCRIPTION
+.sp
+.LP
+The \fBfetestexcept()\fR function determines which of a specified subset of the
+floating-point exception flags are currently set. The \fIexcepts\fR argument
+specifies the floating-point status flags to be queried.
+.SH RETURN VALUES
+.sp
+.LP
+The \fBfetestexcept()\fR function returns the value of the bitwise-inclusive OR
+of the floating-point exception macros corresponding to the currently set
+floating-point exceptions included in \fIexcepts\fR.
+.SH ERRORS
+.sp
+.LP
+No errors are defined.
+.SH EXAMPLES
+.LP
+\fBExample 1 \fRExample using \fBfetestexcept()\fR
+.sp
+.LP
+The following example calls function \fIf\fR( ) if an invalid exception is set,
+and then function \fIg\fR( ) if an overflow exception is set:
+
+.sp

+#include <fenv.h>

+      int set_excepts;              
+      feclearexcept(FE_INVALID | FE_OVERFLOW);
+      // maybe raise exceptions
+      set_excepts = fetestexcept(FE_INVALID | FE_OVERFLOW);
+      if (set_excepts & FE_INVALID) f();
