Gradient offset input field rounding

Inkscape 0.48.3.1 r9886 - W7 x64

Steps to reproduce:
1) Create shape.
2) Add a linear gradient fill.
3) Pull up the "Gradient editor".
4) Hit the "Add stop" button to add a new stop.
5) Now select the new "stop" that was added.
6) In the input field for the offset of the new stop, type in the following number "0.755".

Result:
The input field is rounded up to 0.76, but saved in the file as 0.75999999 for that stop. (To see that long number, save the file first and then open it in an external text editor. I would recommend Notepad++.)

Expected results:
The field should display the setting you selected, 0.755, or at least save 0.755 in your file instead of botching the rounding up process.

So, if Inkscape would have just accepted what the user wanted to input, it would have also saved 5 bytes in the final file size since for some odd reason, when Inkscape rounded 0.755 up to 0.76, it didn't round all the way up and stopped "0.00000001" short.

Also, it gets annoying after awhile when you have to keep going to the external text editor to fix the rounding bug and input there the correct location that you wanted.
