Comments

This method does not take into account specified regional parameters. The . symbol used to divide integral and fractional parts of number should be used in the value passed by the Value parameter; decimal separator is not used.

If conversion fails, an exception is thrown.

To convert real numbers in accordance with the specified regional parameters, use the following methods:

ICultureInfo.ParseDouble
ICultureInfo.TryParseDouble

Example

Var
    d: Double;

    s := "234.234";
    d := Double.Parse(s);
End Sub UserProc;
