Decimal.ToSingle Method (Decimal)
.NET Framework (current version)
Converts the value of the specified Decimal to the equivalent single-precision floating-point number.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- d
-
Type:
System.Decimal
The decimal number to convert.
Return Value
Type: System.SingleA single-precision floating-point number equivalent to the value of d.
This operation can produce round-off errors because a single-precision floating-point number has fewer significant digits than a Decimal.
You can also convert a Decimal to a Single value by using the Explicit(Decimal to Single) assignment operator. Because the conversion can entail a loss of precision, you must use a casting operator in C# or a conversion function in Visual Basic.
The following code example converts Decimal numbers to Single values using the ToSingle method.
// Example of the decimal.ToSingle and decimal.ToDouble methods. using System; class DecimalToSgl_DblDemo { static string formatter = "{0,30}{1,17}{2,23}"; // Convert the decimal argument; no exceptions are thrown. public static void DecimalToSgl_Dbl( decimal argument ) { object SingleValue; object DoubleValue; // Convert the argument to a float value. SingleValue = decimal.ToSingle( argument ); // Convert the argument to a double value. DoubleValue = decimal.ToDouble( argument ); Console.WriteLine( formatter, argument, SingleValue, DoubleValue ); } public static void Main( ) { Console.WriteLine( "This example of the \n" + " decimal.ToSingle( decimal ) and \n" + " decimal.ToDouble( decimal ) \nmethods " + "generates the following output. It \ndisplays " + "several converted decimal values.\n" ); Console.WriteLine( formatter, "decimal argument", "float", "double" ); Console.WriteLine( formatter, "----------------", "-----", "------" ); // Convert decimal values and display the results. DecimalToSgl_Dbl( 0.0000000000000000000000000001M ); DecimalToSgl_Dbl( 0.0000000000123456789123456789M ); DecimalToSgl_Dbl( 123M ); DecimalToSgl_Dbl( new decimal( 123000000, 0, 0, false, 6 ) ); DecimalToSgl_Dbl( 123456789.123456789M ); DecimalToSgl_Dbl( 123456789123456789123456789M ); DecimalToSgl_Dbl( decimal.MinValue ); DecimalToSgl_Dbl( decimal.MaxValue ); } } /* This example of the decimal.ToSingle( decimal ) and decimal.ToDouble( decimal ) methods generates the following output.
