Float to int haskell
WebNumeric literals in Haskell are polymorphic. That means that when you write the literal 3, that could be a Int, Integer (those are Haskell’s big integers), Float, Double, or a whole host of other things. As a result, you may sometimes need to annotate literals with the type that you intend for them to be in order to avoid type ambiguity. Web我正在尝试将一个字符串(数字)转换为单个数字。有多种方法可以解决这个问题,其中一种是map digitToInt "1234" 我尝试了类似的方法,但不是使用digitToInt,而是尝试使用read::Char->Int函数。 然而,当我使用上述函数时,我得到了编译错误,如:
