Hi again:
Another silly program...
#include <iostream>
#include <cln/lfloat.h>
#include <cln/lfloat_io.h>
using namespace cln;
int main(int argc, char **argv)
{
default_float_format=float_format(100);
cl_LF a,b,c;
b="1e-60";
a="1.0";
c=a+b;
std::cerr << "c=" << c << std::endl;
c=c-a;
std::cerr << "c=" << c << std::endl;
}
And the outputs are 1.0L and 0.0L ¿What happen with the
default_float_format?. If I write a="1.00000000000000000000000 ..." (100
zeros here) I obtain the same result, then b is lost somewhere.
More, when b about < 1e-20 then it is lost. Maybe an error in the
conversion?
Bye.
