Hello,

I would like to understand these error messages:
I test 2 function to calculate sin:
when I print:
printf ("%f", sin(PI)) //sin is the sin function I test

the first print this message:
-arena trashed
and the second
-L pointer  (next the program has some bug) //with the sinf of 'single' of the
Cephes Mathematical Library.

I use them (and not the digital mars function that I'm sure has no bug)
because when the sin function of Digital mars is too big for my small exe (not
enough place)

I could make something like:
if( (x==PI) || (x==-PI) )
	{
	return(0.0);
	}
but I would have the bug with sin(3PI) or sin(21PI)

Do you know what these errors are? And how get round these errors?

Thank you very Much.

Thnaks for your answer.
