In perl sin(1) != sin(1.0) or in C or in both?
Also, what version of the OS is this, SunOS 5.8 works fine.
Perl equal and C not equal, that is.
bash-2.03$ perl -le 'if(sin(1) == sin(1.0)){print equal}else{print not equal}'
equal
bash-2.03$ ./sin
not equal
bash-2.03$ cat sin.c
# include math.h
int
main()
{
if(sin(1) == sin(1.0))

printf(equal\n);

else
