ReadDouble: Double;
The ReadDouble method reads real numbers from a binary file.
Executing the example requires the 1.dat binary file to be present in the root of the disc C.
Sub Main;
Var
File1: IFileInfo;
BinR: IBinaryReader;
d: Double;
Begin
File1:=New FileInfo.Attach("c:\1.dat");
If File1.Exists Then
BinR:=File1.OpenBinaryReader;
d:=BinR.ReadDouble;
End If;
Dispose File1;
End Sub Main;
After executing this example, "d" variable contains a real number read from the 1.dat binary file.
