Handle significant figures in VB.NET

Dear all,

  I am trying to handle calculation between numbers, with 25 significant figures (e.g. 123456.7890123456789012345) and seems even double can not handle figures like that.

  Are there any simple way in VB.NET to handle these kind of numbers? except cut the numbers into parts.

  Thanks.

Regs,

Acutally I did use decimal type, but at the begining, it doesn't work, but now I know the reason.

I try the following

Dim x as decimal

x = "123456.7890123456789012345"
msgbox (x + 0.0000000000000000001)

the result will turn out to be 12345.789012346

which I think VB treated 0.0000000000000000001 as double

After assigned 0.0000000000000000001 to another decimal y, then
msgbox(x + y) will give the exact answer

Anyway, thanks for helping
