System Information
Windows 8.1 Update 1
GeForce GTX 550 Ti

Blender Version
Broken: 2.70.f93bc76

Short description of error
Using Cycles render, the checker texture creeps as the scale value increases.

Exact steps for others to reproduce the error
checker.blend
Set render to cycles, keep the default cube
Create a 1000x1000 dimension plane
Set the diffuse color to checker texture
set checker scale to 1000
The render shows the checkers have crept approx 0.5 units in both X and Y.

This happens with both default and UV coordinates.
A workaround is setting the texture scale down to 2 and using UV mapping repeating wrap to scale instead.

*my bad, creep approx 0.05 for 1000 units

Hence a deviation of about 0.005%… We are probably in the float precision area again (though I find it a bit high, maybe too much operations involved?).
