But is _is_ that simple.  Text is Text.

And those numbers aren't integers or floats, they are text strings.
If you want to treat them as numbers, you need to  convert them from
strings into numbers.

int Val1 = atoi(record.firstval);
float Val2 = atof(record.secondval) ;

if( '.' != record.secondval[2] )
	Val2 /= 1000.0;

Or manipulate the strings to add the decimal before doing atof().
