This is the code I was advised and which works well.
It return the value with 6 decimal places even if all of those decimal places are 0. So the result of 36 looks like 36.000000
sprintf(Total, "%f", iTotal);
wsprintf(chTotal, "%s", Total);
SetDlgItemText(hwndDlg, nControl, chTotal);
Also if I try to type more then 6 decimal places it shows no more then 6.
What shall I do now with it? Shall I try some other conversion of types or a method which return only certain number of decimals?
There is a default for %f on how many decimal places it displays, you can control it by specifiying something like "%6.2" - this will give you two decimal places, and the number will be filled with spaces on the right side to make it 6 positions in total.
If you ONLY want decimal places, "%.2f" will give you two decimal places.
I hope this helps.
Yes it work all right thx...
But now I realize there is a problem that the number of decimal places is not constant. I am wondering how to use a variable carring the number of decimals in this case.
Assuming your sprintf is "compatible", you could do:
int positions, decimals;
positions = 6;
sprintf(str, "%*.*f", positions, decimals, value);
Cool now it seems to work without a problem
