26 same type. They might not return the minimum and maximum of their two
27 arguments, if the arguments have different types or have unusual
28 floating-point values. For example, on a typical host with 32-bit 'int',
29 64-bit 'long long', and 64-bit IEEE 754 'double' types:
31 MAX (-1, 2147483648) returns 4294967295.
32 MAX (9007199254740992.0, 9007199254740993) returns 9007199254740992.0.
33 MAX (NaN, 0.0) returns 0.0.
34 MAX (+0.0, -0.0) returns -0.0.
36 and in each case the answer is in some sense bogus. */
