# Convert.ToDecimal Method (Single)

Visual Studio 2010

Converts the value of the specified single-precision floating-point number to the equivalent decimal number.

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

## Syntax

```public static decimal ToDecimal(
float value
)
```

#### Parameters

value
Type: System.Single
The single-precision floating-point number to convert.

#### Return Value

Type: System.Decimal
A decimal number that is equivalent to value.

## Exceptions

ExceptionCondition
OverflowException

value is greater than Decimal.MaxValue or less than Decimal.MinValue.

## Remarks

The Decimal value returned by this method contains a maximum of seven significant digits. If the value parameter contains more than seven significant digits, it is rounded using rounding to nearest. The following example illustrates how the ToDecimal(Single) method uses rounding to nearest to return a Decimal value with seven significant digits.

```
Console.WriteLine(Convert.ToDecimal(1234567500.12F));  // Displays 1234568000
Console.WriteLine(Convert.ToDecimal(1234568500.12F));  // Displays 1234568000

Console.WriteLine(Convert.ToDecimal(10.980365F));      // Displays 10.98036
Console.WriteLine(Convert.ToDecimal(10.980355F));      // Displays 10.98036

```

## Examples

The following example tries to convert each element in an array of Single values to a Decimal value.

```
float[] numbers = { Single.MinValue, -3e10f, -1093.54f, 0f, 1e-03f,
1034.23f, Single.MaxValue };
decimal result;

foreach (float number in numbers)
{
try {
result = Convert.ToDecimal(number);
Console.WriteLine("Converted the Single value {0} to {1}.", number, result);
}
catch (OverflowException) {
Console.WriteLine("{0} is out of range of the Decimal type.", number);
}
}
// The example displays the following output:
//       -3.402823E+38 is out of range of the Decimal type.
//       Converted the Single value -3E+10 to -30000000000.
//       Converted the Single value -1093.54 to -1093.54.
//       Converted the Single value 0 to 0.
//       Converted the Single value 0.001 to 0.001.
//       Converted the Single value 1034.23 to 1034.23.
//       3.402823E+38 is out of range of the Decimal type.
