What does F2 in ToString(“F2”) mean?
The letter F instructs the compiler that the output number string would be displayed up to some fixed point places after the decimal dot. The 2 after the F signifies that the output has to be up to 2 places after the decimal dot, and the number has to be rounded.
For example
double d = 45.3920002;
string s = d.ToString(“F2”);
The output of this would be
45.39
