Description

Single Parse(String) converts the string representation of a number to its single-precision floating-point number equivalent.

Syntax

public static float Parse(
  string s
)

Parameters

Single.Parse(String) has the following parameters.

s - A string that contains a number to convert.

Returns

Single.Parse(String) method returns A single-precision floating-point number equivalent to the numeric value or symbol specified in s.

Example

The following example uses the Parse(String) method to convert an array of strings to equivalent Single values.


//ww  w . j ava  2s  .com
using System;

public class Example
{
   public static void Main()
   {
      string[] values = { "123", "(123)", "-123,456,789", "123.45e+6", 
                          "+543", "5e2", "3.1416", "600.", "-.123", 
                          "-Infinity", "-1E-16", Double.MaxValue.ToString(), 
                          Single.MinValue.ToString(), String.Empty };
      foreach (string value in values)
      {
         try {   
            float number = Single.Parse(value);
            Console.WriteLine("{0} -> {1}", value, number);
         }
         catch (FormatException) {
            Console.WriteLine("'{0}' is not in a valid format.", value);
         }
         catch (OverflowException) {
            Console.WriteLine("{0} is outside the range of a Single.", value);
         }
      }                                  
   }
}

The code above generates the following result.
