[CLN-list] Floating point overflow for cl_R ln (const cl_R& x)

8 Jan 2005

      Hi,

I'm getting some floating point overflow errors when using logarithmic 
functionc l_R ln (const cl_R& x) with big Numbers ( > 20 Stellen).

My code looks like this:

--------------------------------
#include <cln/cln.h>

int main(){

cln::cl_R number_one = 
"41234123412341234123157311812341234124312359123412341";

cln::cl_R number_two = cln::ln (number_one);

std::cout << number_two << std::endl;

return 0;
}
--------------------------------

I compiled with gcc-Version 3.3.5 (Debian 1:3.3.5-4):

	g++ -g -o test -lcln test.cpp

Have I done a mistake or whats the reason why I can't compute those 
values - Is the number too large?
I'm getting a floating point overflow and my debugger tells about 
'Program exited with code 01'

Or is there any other solution?

Thx, Johnny
