Hi,

trying to inhibit floating point underflow exceptions, but it doesn't
seem to work. What am I doing wrong?

#include <cln/cln.h>

int main() {
        cln::cl_inhibit_floating_point_underflow = true;
        cln::cl_N x = 10.0;
        cln::cl_N ep = 100.0;
        cln::cl_N y = cln::expt(x, ep);
        cln::cl_N z = cln::expt(x, -y);
}

Running this program still gives me an underflow exception.

Thanks for any hints.

Jan
