Convert.ToSingle Method (Double)

.NET Framework 4

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

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

Syntax

```public static float ToSingle(
double value
)
```

Parameters

value
Type: System.Double
The double-precision floating-point number to convert.

Return Value

Type: System.Single

Examples

The following example converts each element in an array of Double values to a Single value.

```
double[] values = { Double.MinValue, -1.38e10, -1023.299, -12.98,
0, 9.113e-16, 103.919, 17834.191, Double.MaxValue };
float result;

foreach (double value in values)
{
result = Convert.ToSingle(value);
Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.",
value.GetType().Name, value,
result.GetType().Name, result);
}
// The example displays the following output:
//    Converted the Double value '-1.79769313486232E+308' to the Single value -Infinity.
//    Converted the Double value '-13800000000' to the Single value -1.38E+10.
//    Converted the Double value '-1023.299' to the Single value -1023.299.
//    Converted the Double value '-12.98' to the Single value -12.98.
//    Converted the Double value '0' to the Single value 0.
//   Converted the Double value '9.113E-16' to the Single value 9.113E-16.
//    Converted the Double value '103.919' to the Single value 103.919.
//    Converted the Double value '17834.191' to the Single value 17834.19.
//    Converted the Double value '1.79769313486232E+308' to the Single value Infinity.
