    Default datatype: double

    Now I'm building a calculator for school but I can only go till 8 numbers if I go more then that I get this E9 etc. behind it why is that? I use the datatype double and the windows calculator can go much further then just 8 numbers.. I also want to be able to do that. On google they say I need to do something with the decimal but I can't really figure out what they mean.. What does E9 stand of anyway??

    Thanks in advance, Jimme

    Default Re: datatype: double

    The 'E' stands for 'times 10 raised to the power', so your number reads ... times 10 raised to the power 9. It's 'scientific notation'.

    kind regards,
