.SH DESCRIPTION |
|
20 |
.LP
|
|
21 |
These functions shall determine the maximum numeric value of their |
|
22 |
arguments. NaN arguments shall be treated as missing data: if |
|
23 |
one argument is a NaN and the other numeric, then these functions |
|
24 |
shall choose the numeric value. |
|
25 |
.SH RETURN VALUE |
|
26 |
.LP
|
|
27 |
Upon successful completion, these functions shall return the maximum |
|
28 |
numeric value of their arguments. |
|
29 |
.LP
|
|
30 |
If just one argument is a NaN, the other argument shall be returned. |
|
31 |
.LP
|
|
32 |
If |
|
33 |
\fIx\fP and \fIy\fP are NaN, a NaN shall be returned. |
