ostringstream截断问题 [英] ostringstream truncation problem

问题描述

我正在尝试使用ostringstream将float/double值转换为字符串

ostringstream ostr;
浮点m = 6.9293f;

ostr<< m;

它可以很好地处理这些值:)，但是当我尝试给像3.0f这样的浮点后的值赋值为0时，它只是将值截断为3:confused :.
我不希望这件事发生，我想得到它的原色...:((

i am trying to convert the float/double values to the string using the ostringstream

ostringstream ostr;
float m = 6.9293f;

ostr<<m;

it is working fine with these values :) but when i tried to give values having 0 after floating point like 3.0f it simply truncate the value to 3:confused:.
i dont want this thing to happen i want to get the walues as it is... :((

因为您没有仔细阅读文档.

您必须应用fixed操作器(请参见此处的示例[

Because you didn''t read carefully the documentation.

You have to apply the fixed manipulator (see the example here [^]).
:)

请参阅precision和width运算符. 60％29.aspx> ios类 [ ^ ].

See the precision and width operators of the ios class[^].
