将BigNumber转换为整数，类似于Kotlin

Question

我在Kotlin中有以下代码可以将BigInteger转换为普通的integer

    val bigIntDiv = bigIntVal?.div(BigInteger.valueOf(429496))
    val resultInt = bigIntDiv?.toInt() //This line converts the big Interger down to regular integer

我如何在javascript中实现同样的转换。

我使用的是BigNumber.js库https://github.com/MikeMcl/bignumber.js/，但是我想不出从BigNumber中获取正则整数的方法

这是我目前使用的BigNumber.js库：

let bigIntVal = new BigNumber("5ACDBB4CC493D909F423D779C2C55E7381DFAE6547DCEFE5712F", 16)

现在，我想要从上面Kotlin的等效代码中得到正则整数？

这样：

let regularInteger = bigIntVal.toInt(); //would be the same value as returned from the Kotlin's end?

以获取样本bignumber

5.09632306328228901945340839021510597564609217303391975753746718457743300101444483767019949e

我尝试过使用BigNumber.js库：

let initial = new BigNumber("5.09632306328228901945340839021510597564609217303391975753746718457743300101444483767019949e",16);
let workingVal = initial.toNumber(); //This gives 5.096323063282289e+70, which is not what I want

当我用kotlin编写类似的代码时，kotlin给了我想要的

    val resultInt = initial?.toInt() //Kotlin gave me -1879845894 which is great to work with.

那么，我该如何使用BigNumber.js库来实现同样的功能呢？

下面是一个将bigNumber转换为原始整数的快速示例：

let bigIntVal = new BigNumber("5ACDBB4CC493D909F423D779C2C55E7381DFAE6547DCEFE5712F", 16)
let bigIntValToInt = bigIntVal.toNumber()

// double check
console.log(typeof bigIntVal);
console.log(typeof bigIntValToInt);
