Converts the value of the specified 32-bit signed integer to an equivalent double-precision floating point number.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.Int32
A 32-bit signed integer.
Return Value
Type: System.DoubleA double-precision floating point number equivalent to the value of value.
The following code sample illustrates the conversion of an Int32 value to a Double one, using ToDouble.
Public Sub ConvertDoubleInt(ByVal doubleVal As Double) Dim intVal As Integer = 0 ' Double to Integer conversion can overflow. Try intVal = System.Convert.ToInt32(doubleVal) outputBlock.Text &= String.Format("{0} as an Integer is: {1}", _ doubleVal, intVal) & vbCrLf Catch exception As System.OverflowException outputBlock.Text &= String.Format( _ "Overflow in Double-to-Byte conversion.") & vbCrLf End Try ' Integer to Double conversion cannot overflow. doubleVal = System.Convert.ToDouble(intVal) outputBlock.Text &= String.Format("{0} as a Double is: {1}", _ intVal, doubleVal) & vbCrLf End Sub
