Question

我有一个像这样的十六进制值

如何将其存储在Scala中？

Answer 1

试试BigInt。用法示例：

scala> val i = BigInt("0000030000010000010000020000090000030000040000070000EF", 16)
i: scala.math.BigInt = 18831305580304483748966372317094081267935079240643756687599

scala> i.toString(16)
res3: String = 30000010000010000020000090000030000040000070000ef
