+.SH PROLOG
+This manual page is part of the POSIX Programmer's Manual.
+The Linux implementation of this interface may differ (consult
+the corresponding Linux manual page for details of Linux behavior),
+or the interface may not be implemented on Linux.
+.\"
+.SH NAME
+fegetenv,
+fesetenv
+\(em get and set current floating-point environment
+.SH SYNOPSIS
+.LP
+.nf
+#include <fenv.h>
+.P
+int fegetenv(fenv_t *\fIenvp\fP);
+int fesetenv(const fenv_t *\fIenvp\fP);
+.fi
+.SH DESCRIPTION
+The functionality described on this reference page is aligned with the
+ISO\ C standard. Any conflict between the requirements described here and the
+ISO\ C standard is unintentional. This volume of POSIX.1\(hy2017 defers to the ISO\ C standard.
+.P
+The
+\fIfegetenv\fR()
+function shall attempt to store the current floating-point environment
+in the object pointed to by
+.IR envp .
+.P
+The
+\fIfesetenv\fR()
+function shall attempt to establish the floating-point environment
+represented by the object pointed to by
+.IR envp .
+The argument
+.IR envp
+shall point to an object set by a call to
+\fIfegetenv\fR()
+or
+\fIfeholdexcept\fR(),
+or equal a floating-point environment macro. The
+\fIfesetenv\fR()
+function does not raise floating-point exceptions, but only installs
+the state of the floating-point status flags represented through its
+argument.
+.SH "RETURN VALUE"
+If the representation was successfully stored,
+\fIfegetenv\fR()
+shall return zero. Otherwise, it shall return a non-zero value.
+If the environment was successfully established,
+\fIfesetenv\fR()
+shall return zero. Otherwise, it shall return a non-zero value.
+.SH ERRORS
+No errors are defined.
