[CLN-list] Floating point underflow

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
