Missing value in AddCell()

[Norbert Wołowiec]

When call AddCell method with big number like 31594725 i have in xslsx i have in cell: 31594700

Is that because in xml in package i have <c r="D7" s="6"><v>3.15947e+07</v></c>

To solve this problem, just change this line:m_OStream << '<' << TagName << '>' << Value << "</" << TagName << '>'; to this one: m_OStream << '<' << TagName << '>' << std::fixed << Value << "</" << TagName << '>';

It is possible that in other places this problem also occurs.

Better:

std::setprecision(std::numeric_limits<_T>::digits10 + 1)

Hi,
Sorry for the long answer, I am on a business trip now.
And thanks for your help. Somewhat later, I will check everything well and report it additionally.

I apologize for my long silence, I still have a shortage of free time.
I checked your solution, it works great. Thanks again for helping to develop the library!
I will update the library a little later.
