needed: exponential function with any a real (float) base
hi to all,
I need an exponential function with any a real (floating point) base, similar to exp(x) with Euler's number (e) as a base,
but with any a real base and with any a real exponent, e.g.
I know, there should be a math formula to converse exp(x) to any other real (float) base, but school maths are long gone...
