I try to create a line with two points. These points are obtained in a SHP layer.

How can i convert that points to decimals?

Thank you

Could you clarify what you are looking for? After all, converting a (geometric) point into a "decimal" makes no sense on the face of it. Are you asking, perhaps, for a base-ten decimal representation of point coordinates to be output? (If so, what does that have to do with creating a line [segment] from two points?) –  whuber May 20 '13 at 12:50
    
I take two points from shapefine and I want to create a line with QgsVectorLayer. I need points in decimals to the function QgsGeometry.fromPolyline –  user1573901 May 20 '13 at 13:46

This functionality is covered in "Points2One" and "Points to Paths" plugins. You can take code from there.
