+.SH DESCRIPTION
+.LP
+These functions shall determine the maximum numeric value of their
+arguments. NaN arguments shall be treated as missing data: if
+one argument is a NaN and the other numeric, then these functions
+shall choose the numeric value.
+.SH RETURN VALUE
+.LP
+Upon successful completion, these functions shall return the maximum
+numeric value of their arguments.
+.LP
+If just one argument is a NaN, the other argument shall be returned.
+.LP
+If
+\fIx\fP and \fIy\fP are NaN, a NaN shall be returned. 
+.SH ERRORS
