%d is the type format specifier for signed decimal decimal, for floaing point numbers you can use, for instance, %g. see http://msdn2.microsoft.com/en-us/library/hf4y5e3w(VS.80).aspx[^]
(remember that CString::Format behaves like sprintf).

Don't you like %g?

On my system it works pretty well, anyway, see [^] or [^].

ok,but i need 2 digits 44.66 lets say... then what ?

Use this format tag: %.2f instead.

Don't you read documentation, do you? 
try:
csText.Format("%.2f", nSum);
BTW nSum is a misnaming for a float if you are using Hungarian Notation.

csText.Format("%.2f", nSum);
is not working why?
i have read documentation but is not working !any why ?

What do you mean with the generic is not working? 
Please detail the misbehaviour (i.e. obtained result vs expected result).
BTW Have you correctly declared nSum as floating point number?

Maybe he's new to c++.

try like this:
<br />
float uSum = 12.457 + 345;<br />
CString strFomat;<br />
strFomat.Format(TEXT("%.2f"),uSum);<br />

How can i do that ? lets say in list i have 44.22+44.22 the result must be in csText 88.44 HOW can i do that?
int nSum = 0;
int uSum = 0;
for( int nRow = 0; nRow < m_list1.GetItemCount();nRow++)
{
if(m_list1.GetCheck(/*index of item*/nRow))
{
csText = m_list1.GetItemText( nRow, 2 );
uSum += atoi( csText);
csText.Format("%.2f",uSum);
m_sum.SetWindowText(csText);
}
}
this code give the result : lets say i have in list 44.22+44.22 the result in csText is 88.00 but i need 88.44 HOW ?

don't use atoi(). instead use atof()
I think you must read the documentation rather than starting to build on the project. atoi converts a string to int and not to a float and then when you add them it returns an int in uSum which is just printed as a float value.
Somethings seem HARD to do, until we know how to do them.

ok but... :
uSum += atof( csText);
warning C4244: '+=' : conversion from 'double' to 'int', possible loss of data
Why?
Bravoone

|

|

because nSum has data type int.
|
|
|
|

uSum is an int. so you would need to use typecasting or declare uSum as a float.
I think you are missing on the basics.

It would be better if you read some tutorials on typecasting, using variables and reading some more basics and some more............................and a few more....................

You declare an integer, how would you expect to store a floating point value into it and expect that it still holds a floating point value ? I think you REALLY need to find some good book about the basics of C++. I mean, knowing what an integer and a double are, is at least the bare minimum. It's the thing you learn at very very begining.

WTF !!! can't you understand the error message ??????
Bravoone_2006 wrote: warning C4244: '+=' : conversion from 'double' to 'int', possible loss of data
to int mean you're writing in an int !
you know what ? go by a C/C++ book and learn that language biefore trying to use it any further (or swith to VB )

no, you forget the prerequisite step : learn C++

you must declare uSum as float. and atof() instead of atoi().
<br />
float nSum = 0;<br />
float uSum = 0;<br />
