In HP-UX man pow gives 
      double pow(double x, double y);
so 10 should be 10.0 as an argument to pow, shouldn't it ?


I do not understand the reason for having two versions of pow functions.
HP-UX cc gives error when pow is called without -lm, which I find correct.

Can you, please, explain to me the difference between DJPGG and gnu C ?
I thought DJPGG is just a port of gcc, i.e. a special implementation ?

Thank you
