Have a look here... http://msdn.microsoft.com/en-us/library/0c899ak8.aspx

The ToString method takes a format specifier string that you can use. The characters you're likely interested in are '#' and '0'. With the former, it will tell you to keep that many digits. With the latter, you will keep that many digits and if they don't exist, a zero will be written instead.

Example...
Expand|Select|Wrap|Line Numbers
  1.             Console.WriteLine(Math.PI.ToString());
  2.             Console.WriteLine(Math.PI.ToString("#.####"));
  3.             Console.WriteLine(Math.PI.ToString("000.0000"));
Output:
3.1415926535897 9
3.1416
003.1416
Alternatively, you can use the Math.Round function to actually round the number to the number of decimal places you wish, then call ToString on the result.

Expand|Select|Wrap|Line Numbers
  1.             Console.WriteLine(Math.PI.ToString());
  2.             Console.WriteLine(Math.Round(Math.PI, 2).ToString());
Output:
3.1415926535897 9
3.14

I can google search to find the range of values that can be represented in a float by reading up on the IEEE std, but is that the same as how many distinct values that can go in a float type? For instance, floats can distinguish 0.000001 and 0.000002. If I started with 0.000001 and kept adding 0.000001 until I hit some maximum value (FLT_MAX?) and kept a counter of how many times I added 0.000001, would I have a count of how many...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
