Texture Properties - non integer scaling

When using a displacement modifier, sometimes it's useful to scale the texture by something else than 1,2 or 3 (example 1.35). To acheive a different scale I had to make another set of UV and scale it by hand, for every object. it's tedious and prone to errors. If we "just" had the choice to input something else than a round number, it would make the process easy !
