Help with CString::Format()

[WilliamGS]

Hi all. I am using CString::Format() to convert a double to string:

CString str;
str.Format("%f", 3.14); //The result is "3.14000000" ==> I want "3.14"
str.Format("%f", 202.141); //The result is "202.14100000" ==> I want "202.141"

I do not want the nonsignificant zeros. Is there a way to convert a double to string avoiding nonsignificant zeros?.

Thanks in advance,
William GS.

Format it as:

str.Format("%.2f", 3.14); //2 place precision

str.Format("%.3f", 202.141); //3 place precision

Hi,
>> str.Format("%.2f", 3.14); //2 place precision
>> str.Format("%.3f", 202.141); //3 place precision

It works fine, but I don't know the precision, it could be 0, 1, 2, 3, 4, ...

Use %g instead of %f.
