简单问题！！浮点数如何转化为字符串

[SJLPY]

我用
String str=new String(float);转化不知为何报错！正确方法是什么。

[wandou999]

c.toString();

[kingfish]

Float.toString(f)
or
String s=""+f;

[liujs1026]

String str = String.valueOf(float)

[wangwei8117]

Float.toString(f);方法多呢，要是想输出的话不要转换的，直接加在输出字符后面就可以自动转换输出了，如：System.out.println("ad"+f);这样就可以了！

[diaopeng]

Float.toString(f)

these are two basic methods to convert the types, first, maybe you want to convert the input string to number for use, second, maybe you want to convert the input string by some special encode methods, so just choice the method by your need!
