Hi All: I am using cln with real numbers. I have a problem in the expt function... Wen I have, for example, #include <cln(/real.h> ... cl_R x,y,z; z=expt(x,y); I have problems with the prototypes defined in <real.h> that causes that expt cannot be used in this way. I also can define this function as: cln::cl_R expt(cln::cl_R x, cln::cl_R y) { return exp(x*ln(y)); } And It works fine, but I think that It have to be defined somewhere in the library. Cheers. -- *************************************************************************** * Dr. Isidro Cachadiña Gutiérrez * * Departamento de Física * * Facultad de Ciencias * * Universidad de Extremadura * * 06071 Badajoz ( SPAIN ) * * email: icacha@unex.es * * Teléfono: +34 924 289 300 Ext. 6826 Fax: +34 924 289 651 * *************************************************************************** * Usuario Linux: 8569 * * Para clave pública GnuPG: http://onsager.unex.es/firma.pub.asc * ***************************************************************************
