采用 c#, Manager Directx9.DirectDraw 编写的 模仿windows扫雷的小游戏游戏.-using c#, Manager Directx9.DirectDraw prepared by the imitation windows mine small game game.

his little function rounds a number (or the elements of a vector ot matrix) towards the nearest number with N significant digits. Examples: roundsd(0.012345,3) returns 0.0123 roundsd(12345,2) returns 12000 This is a useful complement to Matlab s ROUND, ROUND10 and ROUNDN (Mapping toolbox), especially when dealing with data with a large variety of order of magnitudes. I was about to upload this file when I found "sd_round.m" by Edward Zechmann (see aknowledgment), which has similar feature (and more). But, because my script is very different in coding (much much shorter), I decided to share it anyway.
