Hi: I was under the impression that on PC'c gcc or g++ implement the 80 bit long double. But how do you use it? I included math.h
WHen I declared long double it does not complain. But when I treid to display it wiht %LE the number of digits is the same as for double. ALso the program does not recognize M_PIl, the long double form of PI which is defined in mathcalls.h. Does it require 128 bit for its use? HAve I to define somewithings with #define ? I am using a Pentium III. Thanks. Sebastian. -- Sebastian Canagaratna Department of Chemistry Ohio Northern University [EMAIL PROTECTED]
