Which function grows faster, exponential or factorial?
154 n! eventually grows faster than an exponential with a constant base (2^n and e^n), but n^n grows faster than n! since the base grows as n increases.
exponential
1e-9 or -1e9, which one is correct?
Neither is more correct than the other. They just represent different values. 1e-9 is 0.000000001; the minus sign applies to the exponent. -1e9 is -1000000000.0; the minus sign applies to the number itself. The e (or E) means “times 10-to-the”, so 1e9 is “one times ten to the ninth power”, and 1e-9 means “one times ten to the negative ninth power”. In mathematical scientific notation, this … Read more
