CString::Format

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

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

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

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

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. ;-)_AnShUmAn_

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

[Bravoone_2006]

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

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....................:rolleyes:

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.

no, you forget the prerequisite step : learn C++ :doh: this guy is f*cking too lazy and keeps asking since months now dumb questions

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 :zzz: )

Thats the tricky part :suss:. If the things remain the same even after learning :laugh:. That could be the reason he isn't trying that.

thanks for your valueable answer. can you give me a working code in this regard please ? :cool:
