In C#, we know that Console.ReadLine() method is used to read string from the standard output device. Then this value is converted into the float type if it is not string type by default. There are different methods available to convert taken input to a float value. Following methods can be used for this purpose:
- Single.Parse() Method
- float.Parse() Method
- Convert.ToSingle() Method
Single.Parse() Method
The Single.Parse() method is used to convert given string value to the float value. This method is consist of the following:
- Single is a class.
- Parse() is its method.
Syntax:
float_value = Single.Parse(Console.ReadLine());
Example: Take input of a float value using Single.Parse() Method
// C# program to Take input // of a float value using // Single.Parse() Method using System;
using System.Text;
public class GFG{
// Main Method
static void Main( string [] args)
{
//declaring a float variables
float value = 0.0f;
// use of Single.Parse() Method
value = Single.Parse(Console.ReadLine());
//printing the value
Console.WriteLine( "Value = {0}" , value);
}
} |
Console Input:
12.34
Output:
Value = 12.34
float.Parse() Method
The float.Parse() method is used to convert given string value to the float value. This method is consist of the following:
- float is an alias of Single class.
- Parse() is its method.
Syntax:
float_value = float.Parse(Console.ReadLine());
Example: Take input of a float value using float.Parse() Method
// C# program to Take input // of a float value using // float.Parse() Method using System;
using System.Text;
public class GFG{
// Main Method
static void Main( string [] args)
{
// declaring a float variables
float value = 0.0f;
// use of float.Parse() Method
value = float .Parse(Console.ReadLine());
// printing the value
Console.WriteLine( "Value = {0}" , value);
}

Console Input:
12.34
Output:
Value = 12.34
Convert.ToSingle() Method
The Convert.ToSingle() Method is used to convert given object to the float value. This method is consist of the following:
- Convertis a class.
- ToSingle() is its method.
Syntax:
float_value = Convert.ToSingle(Console.ReadLine());
Example: Take input of a float value using Convert.ToSingle() Method
// C# program to Take input // of a float value using // Convert.ToSingle() method using System;
using System.Text;
public class GFG{
// Main Method
static void Main( string [] args)
{
// declaring a float variable
float value = 0.0f;
// use of Convert.ToSingle() Method
value = Convert.ToSingle(Console.ReadLine());
// printing the value
Console.WriteLine( "Value = {0}" , value);
}
