Common Data Types

    Hello,

    I am reading beginning ASP.NET in VB 2005 - and I am currently on Common Data Types, page 24. there are a few data types I don't understand.

    Int64 = An integer from -9.2e18 to 9.2e18;
    Single = -3.4e38 to 3.4e38;
    Double = -1.8e308 to 1.8e308

    The thing I don't understand is what the letters inside the integer for? Any help will be greatly appreciated.

    Cheers.

    "e" in this case refers to the exponential of 10 (actually, it is "E", not "e"; both are different).
    E.g. 1E6 = 1000000

    Another example:
    Int64: An integer from -9200000000000000000 to 9200000000000000000
