• [in] env：调用 API 的环境。

  ¥[in] env: The environment that the API is invoked under.

• [in] sign_bit：确定生成的 BigInt 是正数还是负数。

  ¥[in] sign_bit: Determines if the resulting BigInt will be positive or negative.

• [in] word_count：words 数组的长度。

  ¥[in] word_count: The length of the words array.

• [in] words：uint64_t little-endian 64 位字数组。

  ¥[in] words: An array of uint64_t little-endian 64-bit words.

• [out] result：代表 JavaScript BigInt 的 napi_value。

  ¥[out] result: A napi_value representing a JavaScript BigInt.

如果 API 成功，则返回 napi_ok。

¥Returns napi_ok if the API succeeded.

此 API 将一组无符号 64 位字转换为单个 BigInt 值。

¥This API converts an array of unsigned 64-bit words into a single BigInt value.

生成的 BigInt 计算如下：(–1)^sign_bit (words[0] × (2⁶⁴)⁰ + words[1] × (2⁶⁴)¹ + …)

¥The resulting BigInt is calculated as: (–1)^sign_bit (words[0] × (2⁶⁴)⁰ + words[1] × (2⁶⁴)¹ + …)
