its not a issue of grammer, its a issue of (av_)strtod parsing a string and
returning a double. Simply try to awnser if "3.141593" is in bits or bytes
according to this description. It simply makes no sense, the number is
not in bits nor in bytes. Nor does either of them have any meaning here

double pi= av_strtod("3.1415927", NULL); 
is in units of bits?
