does ever make sense set scale negative number this? bigdecimal result; . . . result = result.setscale(-1, roundingmode.half_up) what happens if do? yes, makes sense set scale negative number in situations. means number rounded nearest 10 -scale number, or 10 in case. bigdecimal bd = new bigdecimal(1094); bd = bd.setscale(-1, roundingmode.half_up); system.out.println(bd); system.out.println(bd.doublevalue()); prints 1.09e+3 1090.0 the 1.09e+3 equivalent double value 1090.0 . this useful when scientific measurement quantity has less significant digits total number of digits necessary represent number normally. precision of such number less size of number. if earth's distance sun given 92,960,000 miles, , if value 5 significant digits, equivalent to bigdecimal bd = new bigdecimal(92960000.0); bd = bd.setscale(-3, roundingmode.half_up);// 3 insignificant/imprecise "0" digits system.out.println(bd); which prints 9.2960e+7 ...

writing compute shader used in unity 4. i'm attempting 3d noise. the goal multidiminsional float3 array compute shader c# code. possible in straightforward manner (using kind of declaration) or can achieved using texture3d objects? i have implementation of simplex noise working on individual float3 points, outputting single float -1 1. ported code found here compute shader. i extend work on 3d array of float3's (i suppose closest comparison in c# vector3[,,] ) applying noise operation each float3 point in array. i've tried few other things, feel bizarre , miss point of using parallel approach. above imagine should like. i managed scrawk's implemenation working vertex shaders. scrawk got 3d float4 array shader using texture3d . wasn't able extract floats texture. how compute shaders work well? relying on textures? have overlooked concerning getting values out of texture. seems how user getting data in in this post . similar question mine, not quite i...
