/*
Can anyone tell me why the following program returns a floating point
exception under GCC?  It works fine when compiled under the SCO Xenix
compiler.

My compile command is:
    gcc -w -g -traditional -funsigned-char -o testprog testprog.c
and I am using gcc 1.37.1d

I also noticed that if I change the return line to:
    return (double) (((int) date[6]-'0')*10 + ((int) date[6+1]-'0'));
then it will work fine, but I do not know why.

Thanks

double dom(char *date)
{
    return (double) ((date[6]-'0')*10 + (date[6+1]-'0')); 
}

main()
{
    printf("DAY OF MONTH = %g\n",dom("19901122"));
}
