ruby - 如何使用不等式的 ruby​​ "case ... when "？

Question

你能在 ruby​​ 中做到这一点吗？它似乎“错过”了不平等的情况

 case myvar
 when  myvar < -5
    do somethingA
 when -5..-3
    do special_something_XX
 when -2..-1
    do special_something_YY
 when myvar == 0
    do somethingB
 when myvar > 0
    go somethingC
 end

Answer 1

您正在混合两种不同类型的案例陈述:

case var
when 1
  dosomething
when 2..3
  doSomethingElse
end

case
when var == 1
   doSomething
when var < 12
   doSomethingElse
end
