[GiNaC-devel] Base of natural logarithm

28 Nov 2015

      Hi,

is there a way to create a ginac object "e" such that log(e)
automatically evaluates to 1?

I tried

ex EulernumEvalf() {
  return numeric(cln::exp1());
}
const constant Euler_number("Eulernum", EulernumEvalf, "e",
domain::positive);

Thanks!
