Using textscan with exponential notation

If I have a line of text formatted as follows:

3.3225254e+01 -4.4877079e+01 -4.6426502e+01

How can I use textscan() to pull these numbers out with the same precision?

I've read the text as a string into the variable coord_row, and I've tried this

coord_row = textscan(coord_row,'%f %f %f');

I end up with less precision than I am looking for. I've also tried

coord_row = textscan(A{i},'%9.7f %9.7f %9.7f');

Which lops off the exponential notation.

I want to end up doing some math to the coordinates, and writing back to a file with the same format and precision as the original coordinates I read in. Any help would be greatly appreciated.
