Scala 中的无符号整数 [英] Unsigned integer in scala

问题描述

我要求只存储正值.据我了解，signed 可以存储正值和负值.Scala 中是否有任何无符号整数、双精度数据类型?

I have a requirement to store only positive values. As I understand, signed can store both positive and negative values. Are there any unsigned integer, double data types in Scala?

问候

推荐答案

有人提议在 Scala 中包含新的 unsigned Int 数据类型，但这会对性能产生影响.因此，维护 scala 的人决定不继续在 scala 中使用未签名的 Int 的提议.

There was a proposal to include new data types for unsigned Int in scala, but it was going to have a performance impact. Hence the people who maintain scala decided not to go ahead with the proposal of an unsigned Int in scala.

请参考以下https://docs.scala-lang.org/sips/unsigned-integers.html

您还可以参考 Scala 中的无符号变量.
