   `SIMDJSON_MINUS_ZERO_AS_FLOAT` to on: `cmake -B build -D SIMDJSON_MINUS_ZERO_AS_FLOAT=ON`.
-* **Big Integer Support (opt-in):** By default, integers that exceed the 64-bit range cause parsing to fail with `BIGINT_ERROR`. You can opt in to big integer support so that these numbers are stored as raw digit strings on the tape instead:
-  ```cpp
-  simdjson::dom::parser parser;
-  parser.number_as_string(true); // opt-in, default false
-  simdjson::dom::element doc;
-  auto error = parser.parse("[1, 123456789012345678901]"_padded).get(doc);

-  When enabled, big integers have type `element_type::BIGINT`. Calling `get_int64()`, `get_uint64()`, or `get_double()` on a big integer returns `INCORRECT_TYPE`. Normal numbers (int64, uint64, double) are unaffected.

Numbers are serialized as 64-bit floating-point numbers (`double`).

 Performance consideration: We store numbers of the main tape because we believe that locality of reference is helpful for performance.
 
-## Big Integers
-
-When a JSON integer exceeds the 64-bit range (both signed and unsigned), it is classified as a big integer. By default, parsing returns `BIGINT_ERROR`. When `parser.number_as_string(true)` is set, the raw digits are stored on the string tape using the same format as strings (4-byte little-endian length prefix, followed by the UTF-8 digit bytes, followed by a null terminator).
-
-A big integer is represented on the main tape as the 64-bit tape element `('Z' << 56) + x` where the payload `x` is the location on the string tape of the null-terminated digit string.
-
-For example, the JSON value `99999999999999999999` would be stored as the string `"99999999999999999999"` on the string tape, with a `'Z'` tag on the main tape. Negative big integers include the leading minus sign.
-
 ## Root node
 
 Each JSON document will have two special 64-bit tape elements representing a root node, one at the beginning and one at the end.
