Hi! I've been solving a problem on C# and a one problem had gone off. I need to decrease number of digits of a float variable.
for example:
If I have 14.3413543485
I wanna make it just 14.34.
My Informatic teacher says there is a way, but he'd forgot it. Could you, please, help me?

I am not sure of the commands, because I've only just started programming in C#, but I can give you something you could use.

Let's say your number is x=12.5742165 and you want it to be x=12.57. Here's a formula to use:

x=trunc(x*100)/100

Don't know if trunc is the right command, but you need one that removes the part after the '.'
This way, you get x=1257/100 and that is 12.57

There's a very easy way to do this in C# - by passing a certain parameter to the ToString method that is part of any given data type or canonical class.

For example:
CODE

// val contains your given value
int val = 14.3413543485;

// we declare a string that contains the truncated value
string decimal_adjusted = val.ToString ( "N2" );


The resultant value in decimal_adjusted should be 14.34.

The N2 value passed to the ToString method tells it to treat the value stored in val as a Numeric value and cut it down to 2 decimal places.

You can replace 2 with whatever your desired degree of truncation is. If you want upto 3 decimal places, it should be N3, for 5 decimal places, N5 and so on.

But if number is negative then val.ToString("N2"); returns 0. /Any solution for this?

Thats easy enough. The trick is in converting the number to string and then taking out one character at a time using the string type's substring method in a loop. Use the counter variable to check if the current position is odd or even and correspondingly add the digit to the running sum of Even or Odd numbers. Given below is the code.

CODE
using System;

class Program
{
    static void Main(string[] args)
    {
        Console.Write("Enter the number:");
        int Num = Convert.ToInt32(Console.ReadLine());
        string NumInString = Num.ToString();
        int OddSum = 0, EvenSum = 0;

        for (int i = 0; i < NumInString.Length; i++)
        {
            int Digit = Convert.ToInt32(NumInString.Substring(i, 1));
            if (i % 2 != 0)
                EvenSum += Digit;
            else
                OddSum += Digit;
        }

        Console.WriteLine("Odd Sum = {0} Even Sum = {1}", OddSum, EvenSum);
        Console.Read();

    }
}

Your method seems excessive, why not just retrieve the value and then truncate it. While it probably doesn't matter for the scope of his problem, using loops while going through massive data can be taxing on resources. Granted the first explanation wasn't very good, but if you look up the truncate function in the Microsoft C# reference library it will explain how to use it, I'm sure it will fit your needs.

@Sandip is there a reason you can't truncate the value? If so please post it and I'll give you some more feedback.
