Console.WriteLine(y)
when I input x and y
big number for example
x= 123123123123
y= 123123123123
the resoult will be 1,51593034475614E+22

and when i has correct the code to
Dim x As Double
Dim y As Double
x = Console.ReadLine()
y = Console.ReadLine()


y = y * x

Console.WriteLine(y.ToString("n10"))

but the correct resaulrt is 15159303447561417273129

The sad truth is that vb won't handle more numbers so the result won't be exact. However you could do walkarounds to this problem with special made structures/classes. I haven't tried it myself but it seems that there's a built in structure for this called BigInteger: BigInteger Structure (System.Numerics)
