在Ruby中有符号和无符号整数 [英] Signed and Unsigned Integers in Ruby

问题描述

与C一样，不红宝石已经签署和无符号整数，如果是的话那么确实有符号整数的String类回报平均长度的方法？ （由于用C整数如果没有指定意味着签字）

Like C , does ruby have signed and unsigned integers and if it does then does that mean length method of String class return signed integer ? (Since in C integer if not specified implies signed)

推荐答案

红宝石实现了这样的方式的区别符号整数/无符号是不相关的，如红宝石整数自动伸入BIGNUM（任意长度的整数）时适用。

Ruby implements integers in such a way that the distinction signed/unsigned is irrelevant, as Ruby integers extend automatically into BigNum (arbitrary length integers) when applicable.

这有效地prevents整数溢出，这是恕我直言，最主要的原因，人们关心与固定大小的整数像C语言符号性。

This effectively prevents integer overflow, which is IMHO the main reason why people care about signedness in languages with fixed-size integers like C.
