+.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
+floor,
+floorf,
+floorl
+\(em floor function
+.SH SYNOPSIS
+.LP
+.nf
+#include <math.h>
+.P
+double floor(double \fIx\fP);
+float floorf(float \fIx\fP);
+long double floorl(long double \fIx\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\(hy2008 defers to the ISO\ C standard.
+.P
+These functions shall compute the largest integral value not greater
+than
+.IR x .
+.SH "RETURN VALUE"
+The result shall have the same sign as
+.IR x .
+.P
+Upon successful completion, these functions shall return the largest
+integral value not greater than
+.IR x ,
+expressed as a
+.BR double ,
+.BR float ,
+or
+.BR "long double" ,
+as appropriate for the return type of the function.
+.P
+If
+.IR x
+is NaN, a NaN shall be returned.
+.P
+If
+.IR x
+is \(+-0 or \(+-Inf,
+.IR x
+shall be returned.
+.SH ERRORS
+No errors are defined.
+.LP
+.IR "The following sections are informative."
+.SH EXAMPLES
+None.
+.SH "APPLICATION USAGE"
+The integral value returned by these functions might not be expressible
+as an
+.BR intmax_t .
+The return value should be tested before assigning it to an integer
+type to avoid the undefined results of an integer overflow.
+.P
+These functions may raise the inexact floating-point exception if the
+result differs in value from the argument.
+.SH RATIONALE
+None.
+.SH "FUTURE DIRECTIONS"
+None.
