Hello, This shows one way of interpreting the derivative for strictly +ve numbers. public static void main(final String[] args) { final double x = 1d; DerivativeStructure dsA = new DerivativeStructure(1, 1, 0, x); System.out.println("Derivative of |a|^x wrt x");

Hi! IMHO, 0^x should equal 0. But note please, that 0^0 is not define, so it should be NaN --- TIA, Rodion Ajo Fod писал 23.08.2013 05:17 PM: Seems like the DerivativeCompiler returns NaN. IMHO it should return 0. Is this worthy of an issue? Thanks, -Ajo ---
