Convert.ToSingle Method (Double)

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)

public static float ToSingle(
	double value
)

Parameters

value
Type: System.Double

The double-precision floating-point number to convert.

Return Value

Type: System.Single
A single-precision floating-point number that is equivalent to value.
value is rounded using rounding to nearest. For example, when rounded to two decimals, the value 2.345 becomes 2.34 and the value 2.355 becomes 2.36.

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.
