Convert float to LPCWSTR/LPWSTR

Question

[win 32 C++]

I don't know how to convert float to LPCWSTR/LPWSTR or LPCWSTR <-> LPWSTR

Thanks a lot

Answer 1

is there a wsprintf function available?

Answer 2

#include <sstream>
...
float f = 45.56;
wstringstream wss;
wss << f;
// wss.str().c_str() returns LPCWSTR
cout << wss.str() << endl;
...

Answer 3

Check out the official MSDN pages for floating point support here and for data conversion here - a bonus link - here's the MSDN page for string functions (including multibyte support).

Answer 4

The native Win32 API doesn't have any functions for printing floating point values, but there's a more recent addition called strsafe which has StringCchPrintf

TCHAR buffer[24];
StringCchPrintf(buffer, sizeof(buffer)/sizeof(TCHAR), "%f", float_value);
