Heh, so NaN is, pretty literally, “not a number”, but infinity is ? Math-wise at least that doesn’t make sense, infinity has a meaning as a notation in the context of limits, but it’s neither a number nor even a value. Python-wise, we already treat nan and the infs as a special thing, in the floor, ceil, round and int functions. All those …

WebbI dag · math.floor(x) ¶. Return the floor of x, the largest integer less than or equal to x. If x is not a float, delegates to x.__floor__, which should return an Integral value. math.fmod(x, y) ¶. Return fmod (x, y), as defined by the platform C library. Note that the Python expression x % y may not return the same result. Webbscipy.integrate.dblquad(func, a, b, gfun, hfun, args=(), epsabs=1.49e-08, epsrel=1.49e-08) [source] #.
