'Declaration <CLSCompliantAttribute(False)> _ Public Shared Function ToDouble ( _ value As ULong _ ) As Double
Parameters
- value
- Type: System.UInt64
The 64-bit unsigned integer to convert.
Return Value
Type: System.DoubleA double-precision floating-point number that is equivalent to value.
The following example converts each element in an array of UInt64 values to a Double value.
Dim numbers() As ULong = { UInt64.MinValue, 121, 12345, UInt64.MaxValue } Dim result As Double For Each number As ULong In numbers result = Convert.ToDouble(number) Console.WriteLine("Converted the UInt64 value {0} to {1}.", _ number, result) Next ' The example displays the following output: ' Converted the UInt64 value 0 to 0. ' Converted the UInt64 value 121 to 121. ' Converted the UInt64 value 12345 to 12345. ' Converted the UInt64 value 18446744073709551615 to 1.84467440737096E+19.
