String to Float in C# (Various ways)

In previous article, I mentioned how to Set Default Value to Property in C# but in this article, I have mentioned how we can convert string to float in C# using various possible ways with console application example.

First, I will create a console application in .NET Core, so you can open your Visual Studio 2019/2022 and then create new console application.

Using Float.parse()

Float.parse() method, converts the string representation of a number to its single-precision floating-point number equivalent.

using System;
using System.Globalization;

namespace StringToFloat
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var strNumber = "44.5696";
            var convertedFloat = float.Parse(strNumber, CultureInfo.InvariantCulture.NumberFormat);
            Console.WriteLine(convertedFloat);
        }
    }
}

Output:

44.5696

Using Convert.ToDouble()

Although, Convert.ToDouble() method is used to convert value to double, but we can still use to convert string to float in C#.

It Converts a specified value to a double-precision floating-point number. 

Here is the complete working example using it

using System;

namespace StringToFloat
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var strNumber = "44.5696";
            var convertedFloat = (float) Convert.ToDouble(strNumber);
            Console.WriteLine(convertedFloat);
        }
    }
}

Output:

44.5696

Note: Precision of float number is 7 digits. If you want to keep the more digits after decimal, you need to use the double type which can keep 15-16 digits.

Using Convert.ToSingle()

Convert.ToSingle() method Converts a specified value to a single-precision floating-point number.

Example:

using System;

namespace StringToFloat
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var strNumber = "44.5696";
            float convertedFloat = Convert.ToSingle(strNumber);
            Console.WriteLine(convertedFloat);
        }
    }
}

Output:

44.5696

That's it, hope this helps.
