java - scala给BigInt赋初值失败？

Answer 1

问题不在BigInt, 是右边那个字面量无法求值.

scala> 1881676371789154860897069000
<console>:1: error: integer number too large
1881676371789154860897069000

BigInt可以用字符串初始化

scala> BigInt("12345667890087234578023089723457234705892375071881676371789154860897069000")
res0: scala.math.BigInt = 12345667890087234578023089723457234705892375071881676371789154860897069000
