I want to convert float value to string.
Below is the code which i am using for the conversion.
static void Main(string[] args)
{
string s =string.Format("{0:G}", value);
Console.Write(s);
Console.ReadLine();
}
and it outputs as 2.5
But my problem is i want to get the value as 2.50 because i want to compare it with original value later in my project.
so please suggest me if there are any ways to do it?

We can convert float and double to string using the C++11 std::to_string() function. For the older C++ compilers, we can use std::stringstream objects.
In Python, we can use str() to convert float to String.
We can convert String to float in java using Float. parseFloat() method.
We can convert a float to String using any of the following two methods: 1) Method 1: Using String. valueOf(float f): We pass the float value to this method as an argument and it returns the string representation of it.
Use the std::to_string () Method to Convert a Float to a String in C++. The to_string function is defined in <string> header and can convert various numeric types to a string value. The method takes a numeric value as a parameter and returns std::string value. Note that, to_string may return unexpected results as the number of significant ...
There are three methods to convert Float to String: Method 1: Using DataFrame.astype (). This is used to cast a pandas object to a specified dtype.
We can also notice that the conversion follows the list as stated above “Float -> List -> String.” Here the str method is used to convert to the string data type. The join method takes all the methods in iterable and joins them to make a string. To perform this process this operation, the following methods are used.
Float is a datatype that holds floating-point values whereas String is a sequence of characters and a class in Java. To convert Float to String there are several ways like the valueOf () method of String class or toString () method of Float class or a simple string literal that converts an expression to string.
You should be using {0:N2} to format to two decimal places.
string.Format("{0:N2}", 2.50)
For 3 decimal places:
string.Format("{0:N3}", 2.50)
And so on.
You can also store the value in a string this way without worrying about precision and then convert your value where you are testing for comparison as string:
string strDecimalVal = Convert.ToString( 2.5000001);
because i want to compare it with original value later in my project.
...then you will need to store the number of decimal places the original value had. Once the value is a float, this information is lost. The float representations of 2.5, 2.50 and 2.500 are exactly the same.
So, basically, you have the following possibilities (in order of preference):
myFloat.ToString("F" + numDecimals.ToString()) to convert it to a string.Alternatively, if you do not insist on using floats, decimals might suit your purpose: The do store the number of significant digits:
decimal x = Decimal.Parse("2.50", CultureInfo.InvariantCulture);
decimal y = Decimal.Parse("2.500", CultureInfo.InvariantCulture);
Console.WriteLine(x.ToString()); // prints 2.50
Console.WriteLine(y.ToString()); // prints 2.500
Try this
Console.WriteLine("{0:F2}", 2.50);
Console.WriteLine("{0:0.00}", 2.50);
Console.WriteLine("{0:N2}", 2.50);
Version 1 and 2 are almost similar, but 3 is different. 3 will include number separators when number is large.
For example the following outputs 454,542.50
Console.WriteLine("{0:N2}", 454542.50);
