For instance, if country A (foreign currency) has an inflation rate of 5%, country B (domestic currency) has an inflation rate of 3%, and no changes in the nominal exchange rate took place, then country A (foreign currency) now has a currency whose real value is approximately 2% higher than before.（例如，如果A国（外币）的通货膨胀率为5％，B国（国内货币）的通货膨胀率为3％，名义汇率没有变化，那么A国（外币） 现在有一种货币，其实际价值比以前高出约2％。），这个不应该是B国货币升值吗？ 为啥写的是A 国货币的实际价值比以前高2%， A国货币不应该是贬值2%吗？？
