Yes, thanks.
But I was talking about mathematical definitions and these are CS standards. For instance: pure math has no big notion of floating point numbers. Personally I'm fine with allowing root($x,$o) with $x<0 and $o odd integer in a computer. But I could imagine reasons in the realm of mathematical modeling of functions to consider them undefined. > the second argument has a non-integer value I'd say because there is no way to express 1/$o loss free as binary floating point number ('$o odd integer')
