.SH DESCRIPTION
|
|
.LP
|
|
These functions shall determine the minimum 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 minimum
|
|
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.
|
