System Information
Win8.1x64, 3x gtx580

Blender Version
2.77a

Short description of error
Not exactly a bug but makes it quite limiting.
In Cycles render settings -> volume sampling -> step size displays values down to 0.01 which is way too coarse. It needs an order or two of precision more.

Strangely that works. However, try entering 0.012, 0.017, 0.01111 - it returns 0.01, 0.02 etc.

If you type in 0.012 it actually holds it but displays 0.01

If you type it in, hover over the box, press ctrl-c, then paste the value into a text editor / box somewhere, it will show the absolute value.

So it is usable and the actual value is retrievable. Not the end of the world then. Thanks.
Though is there a reason to rounding it this way? I mean it's a direct input value, not a generated one, thus any weird number gets entered exactly as intended.
