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.
Upon successful completion, these functions shall return the maximum numeric
value of their arguments.
If just one argument is a NaN, the other argument shall be returned.
If
x and
y are NaN, a NaN shall be returned.
