# Decimal Explicit Conversion (Decimal to Single)

Silverlight

Converts a Decimal to a single-precision floating-point number.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

## Syntax

```public static explicit operator float (
decimal value
)
```

#### Parameters

value
Type: System.Decimal
A Decimal to convert.

#### Return Value

Type: System.Single
A single-precision floating-point number that represents the converted Decimal.

## Remarks

This operation can produce round-off errors because a single-precision floating-point number has fewer significant digits than a Decimal.

This operator supports the explicit conversion of a Decimal to a Single. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to a Single value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the ToSingle or the Convert.ToSingle(Decimal) method.

## Examples

The following code example converts Decimal numbers to Single values using the explicit Decimal to Single conversion.

```
// Example of the explicit conversions from decimal to float and
// decimal to double.
using System;

class Example
{
static string formatter = "{0,30}{1,17}{2,23}";

// Convert the decimal argument; no exceptions are thrown.
public static void DecimalToSgl_Dbl(System.Windows.Controls.TextBlock outputBlock, decimal argument)
{
object SingleValue;
object DoubleValue;

// Convert the argument to a single value.
SingleValue = (float)argument;

// Convert the argument to a double value.
DoubleValue = (double)argument;

outputBlock.Text += String.Format(formatter, argument,
SingleValue, DoubleValue) + "\n";
}

public static void Demo(System.Windows.Controls.TextBlock outputBlock)
{
outputBlock.Text += String.Format(
"This example of the explicit conversions from decimal " +
"to float \nand decimal to double generates the " +
"following output. It displays \nseveral converted " +
"decimal values.\n") + "\n";
outputBlock.Text += String.Format(formatter, "decimal argument",
"float", "double") + "\n";
outputBlock.Text += String.Format(formatter, "----------------",
"-----", "------") + "\n";

// Convert decimal values and display the results.
DecimalToSgl_Dbl(outputBlock, 0.0000000000000000000000000001M);
DecimalToSgl_Dbl(outputBlock, 0.0000000000123456789123456789M);
DecimalToSgl_Dbl(outputBlock, 123M);
DecimalToSgl_Dbl(outputBlock, new decimal(123000000, 0, 0, false, 6));
DecimalToSgl_Dbl(outputBlock, 123456789.123456789M);
DecimalToSgl_Dbl(outputBlock, 123456789123456789123456789M);
DecimalToSgl_Dbl(outputBlock, decimal.MinValue);
DecimalToSgl_Dbl(outputBlock, decimal.MaxValue);
}
}
