Parameters

format

A string that specifies the format of the returned string.

Note: For a list of valid values, see float.ToString (string, IFormatProvider ).

Returns

A string representation of the current instance formatted as specified by format . The string takes into account the current system culture.

Exceptions

Type	Reason
FormatException	format is invalid.

Remarks

This version of float.ToString is equivalent to float.ToString (format, null ).

If format is a null reference, the general format specifier "G" is used.

Example

The following example shows the effects of various formats on the string returned by float.ToString .

C# Example

using System;
class test {
 public static void Main() {
   float f = 1234.567f;
   Console.WriteLine(f);
   string[] fmts = {"C","E","e5","F","G","N","P","R"};
   for (int i=0;i<fmts.Length;i++)
     Console.WriteLine("{0}: {1}", 
       fmts[i],f.ToString(fmts[i]));
 }
}
   

The output is

1234.567
C: $1,234.57
E: 1.234567E+003
e5: 1.23457e+003
F: 1234.57
G: 1234.567
N: 1,234.57
P: 123,456.70 %
