    17, to be specific.

    If you haven't yet, go check this one out:

    http://forum.dashnet.org/discussion/16040/in-what-range-is-your-favorite-number

    It allows you to be more specific, but only if your favorite is actually a real number, and is at least 1.

    I actually can't really answer yet (assuming complex etc. refers to the non-real complex numbers) but I chose the most likely option for the Euler–Mascheroni constant.
    Maybe some time in the future somebody clever will prove if it really is irrational.
    That is one of the reasons it is my favourite number. It appears in many places in maths yet nobody has ever proven it to be irrational.

    This thread is very suspicious
    There is illuminatic force here




    No.
    My favourite number is not 13, it's 666, now stay away before I kell u

    Any of the octonions.

    Explanation of an octonion:
    You know about the number line, right? I will assume so.

    The square root of -1, which is i, extends that number line to a number plane, with on axis being all of the real numbers, and the oher axis being all of the real multiples of i. The points not on the axis but still on the plane are some value of i multiplied by some other real value. In here there will not only be irrational numbers, but also negative imaginary irrational numbers multiplied by irational numbers to give some pretty weird values. I think Vsauce or Numberphile did a video explaining some pretty weird properties of this plane, with magic triangles that can be used to multiply to random points on the plane together. Crazy stuff.

    Quaterions are what happen when you take that number plane, and extend it into four dimensions. There is no three dimensional version of this, because that would be the same as multiplying i by itself, or i squared which just gives -1, a real number that can fit in on our original number plane. In quaternion land, there is i, j, and k. There is a really interesting property that quaterions have. i*j=k, but j*i=-k, which can lead to more interesting areas of maths to play around in.

    Octonions are what happen when that 4D space becomes 8D. Now you get to some really crazy and complex stuff which I haven't quite managed to wrap my head around,
    but it is still really fun to learn about. Surprisingly, you can't extend the number space past eight dimensions, it stops here. You would think that you can, at first it seems intuitively obvious, but for some reason I again haven't quite gotten around to learning about, it can't go any farther.

    Actually you can but it loses more algebraic properties. 16-D numbers are called sedenions. They lose the alternative property so x(xy) may not equal (xx)y. It can be continued on an infinite number of times but nothing past octonions will be an alternative algebra 32-D would be called something like duotriginions. But apparently past 16-D it isn't very interesting so they haven't been given an official name.

    Edit:
    Octonions lose the associative property so a*(b*c) may not equal (a*b)*c

    Edit2:
    I read some more and sedenions are even weirder. Multiplying 2 non-zero sedenions can give zero.
