[gexiv2] gexiv2 decimal digits in the GPS tags

[Eyal Saiet <ejsaiet alaska edu>]

Hello gexiv community,

I am a bit confused why am a I writing numbers with a certain length of digits after the decimal point, and when I read the I get more than I wrote. Example is easier to explain:

>>> y_loc=71.377951137 ; m.set_gps_info(float(x_loc),float(y_loc),float(z_loc));m.get_gps_latitude()

True

71.37795113694443

Why is get_gps_latitude() return more digits than was written?

Is there some calculation going on in your module that cannot return the exact value?

I thought Exif header can only accept degree, minute, decimal seconds?!

Thanks
