I have strings that are something like

to do this, but if just seems so sloppy.
This is a code snippet that extracts the numbers. Can't I change the
delimitor for the istringstream class? I'm overwhelmed with a lot of data
on the strings and iostream libraries, but not enough context.
eh - Pan "fixed" the code
double day_weight;
string day_weight_unit;
istringstream stream1;
stream1.clear();
stream1.str(mgkgperday);
string errorstg = "Can't find rate per day";
try{
//15meq/kg/day
if(! stream1 >> ws >> day_weight )
{ throw errorstg;
}
if(! stream1 >> ws >> day_wright_unit){
throw errorstg;
}
}catch (string errorstg){
cout << errorstg << "mg/kg/day";
}
}
//total weight of lyte needed in 24 hours;
const string ml = "ml";
double twgt = mgkgperday * c_pt_wgt;
//cast float to double double
tvol_per_day = rate_ml_hr * 24; double needed_wgt, total_bags_vol;
int number_of_bags;

You must be a stupid engineer then, because politcs and technology have been attached at the hip since the 1st dynasty in Ancient Egypt. I guess you missed that one."
