This is not a bug in Lua. It's a limitation of floating point arithmetic.
Neither 235.7 nor 0.05 have exact representation in floating point:
> print(string.format("%.20f",235.7))
235.69999999999998863132
> print(string.format("%.20f",0.05))
0.05000000000000000278
See for instance http://floating-point-gui.de .
