#4 Arbitrary base logarithm

2016-04-25T16:29:32.489000Z

Hello,

As you may know, you can calculate the logarithm of x in base y by the following: ln(x)/ln(y).

Currently we have, as you noted, two logarithm functons ln(x [, espilon]) and log(x [, epsilion]). Perhaps addiing 3rd function .. oh say call it logb(x, base [, epsilon]), where the 2nd base argument is required could return ln(x)/ln(base) for you.

I'm not sure what the best name for this buildin function. Alas we cannot use ln() nor log() because today their 2nd argument, if given, is the epsilon error term. So maybe we can use lnb(x,base[,ep]) or maybe logb(x,base[,ep]) or ???

Arbitrary base logarithm

Is there a way to calculate arbitrary base logarithm and not just base 10 or e?

C++ wrapping for boost

2009-06-02T09:15:28Z

The templatized boost libraries provide computing of special functions (gamma, statistical fi), for any kind of 'real' numbers
A wrapping C++ class around calc would allow to use these function easily.
Has somebody developed something like this ?

Is there a euler constant function?

2009-01-26T03:53:42Z

Is there a euler constant (e = 2.718...) function? I've found both euler() and freeeuler() builtin functions, but they both seem to be completely unrelated. There is a pi() function that returns the pi constant, it seems unlikely that there would not be a builtin for e.

So is there one? How do I use it?

how to print the result in binary format?

Hi guys, thanks for developing apcalc.
I don't know how to print the result in binary format.

Please help.

thanks!
