# How to Convert Int to Float with 2 Decimal Places in C#?

Do you need to know how to convert int to float with 2 decimal places in C#? Check out this complete tutorial. I have explained here different methods in C# to convert int to float with 2 decimal places.

To convert an integer to a float with two decimal places in C#, you can use the ToString method with a format specifier. For example:

int myInt = 123;
float myFloat = myInt;
string myFloatWithTwoDecimals = myFloat.ToString("0.00");

This code snippet converts the integer myInt to a float and then formats it as a string with two decimal places.

## Convert Int to Float with 2 Decimal Places in C#

Here are 6 different methods in C# convert int to float with 2 decimal places with examples and complete code.

### 1. Using float.Parse() and String.Format()

One of the simplest ways to convert an integer to a float with two decimal places in C# is to first convert the integer to a string and then parse it as a float.

using System;

class Program
{
static void Main()
{
int myInt = 123;
float myFloat = float.Parse(myInt.ToString());
string myFloatWithTwoDecimals = String.Format("{0:0.00}", myFloat);
Console.WriteLine(myFloatWithTwoDecimals); // Output: 123.00
}
}

In this method, myInt.ToString() converts the integer to a string. float.Parse() then converts the string back into a float. Finally, String.Format() formats the float to two decimal places.

You can see the output in the screenshot below:

### 2. Using Division and Math.Round()

Another way to achieve this is by dividing the integer by 1.0 to get a float and then rounding it to two decimal places using Math.Round() in C#.

using System;

class Program
{
static void Main()
{
int myInt = 123;
float myFloat = myInt / 1.0f;
float myFloatWithTwoDecimals = (float)Math.Round(myFloat, 2);
Console.WriteLine(myFloatWithTwoDecimals); // Output: 123.00
}
}

Here, dividing by 1.0f explicitly converts the integer to a float. Math.Round() is then used to round the number to two decimal places.

### 3. Using String Interpolation

C# 6 introduced string interpolation, which provides a more readable and convenient syntax to create formatted strings.

using System;

class Program
{
static void Main()
{
int myInt = 123;
float myFloat = myInt / 1.0f;
string myFloatWithTwoDecimals = \$"{myFloat:0.00}";
Console.WriteLine(myFloatWithTwoDecimals); // Output: 123.00
}
}

The \$ before the string starts the string interpolation, and the {myFloat:0.00} inside the string is the interpolation expression that formats the float.

### 4. Using Convert Class

The Convert class provides a method to convert various base data types to other base data types in C#. After converting to a float, you can then format it to two decimal places.

using System;

class Program
{
static void Main()
{
int myInt = 123;
float myFloat = Convert.ToSingle(myInt);
string myFloatWithTwoDecimals = myFloat.ToString("0.00");
Console.WriteLine(myFloatWithTwoDecimals); // Output: 123.00
}
}

In this snippet, Convert.ToSingle(myInt) converts the integer to a float in C#. Then, ToString("0.00") formats the float to two decimal places.

### 5. Using Custom Extension Method

You can also create a custom extension method to encapsulate the conversion logic, making your code cleaner and reusable.

using System;

class Program
{
static void Main()
{
int myInt = 123;
float myFloatWithTwoDecimals = myInt.ToFloatWithTwoDecimals();
Console.WriteLine(myFloatWithTwoDecimals); // Output: 123.00
}
}

public static class ExtensionMethods
{
public static float ToFloatWithTwoDecimals(this int value)
{
return (float)Math.Round(value / 1.0f, 2);
}
}

Here, ToFloatWithTwoDecimals is an extension method that converts the integer to a floating-point number and rounds it to two decimal places.

### 6. Using decimal for More Precision

If you need more precision, you can use the decimal type instead of float. The decimal type has a larger range and precision which is ideal for financial and monetary calculations.

using System;

class Program
{
static void Main()
{
int myInt = 123;
decimal myDecimal = myInt;
decimal myDecimalWithTwoDecimals = Math.Round(myDecimal, 2);
Console.WriteLine(myDecimalWithTwoDecimals); // Output: 123.00
}
}

In this example, Math.Round() is used to round the decimal to two decimal places in C#.

## Conclusion

Converting an integer to a float with two decimal places in C# can be done in several ways like String.Format(), the newer string interpolation, or the precision of the decimal type, etc.
