        "-57896044618658097711785492504343953926634992332820282019728792003956564819968"

assert_eq!(
    int!(
        "0x7fff_ffff_ffff_ffff_ffff_ffff_ffff_ffff
           ffff_ffff_ffff_ffff_ffff_ffff_ffff_ffff"
    ),
    I256::MAX,
);
assert_eq!(int!("0b101010"), 42);
assert_eq!(int!("-0o52"), -42);
