      <precision>[,<y_precision>,<z_precision>]) 
   
Arguments
            
   <axis>   
   
      The first parameter controls the axis of the coordinates being rounded. If 
      xyz is specified, then the respective precision values will be used for 
      each axis.
   
      Range: (x|y|z|xyz)   
      
   <precision> 
   
      The second parameter controls the number of decimal places of precision to 
      which the coordinates are rounded. A value of 0 causes all coordinates 
      along the specified axis to be rounded to the nearest integer. If the axis 
      is specified as xyz, then this precision value will be used for the x 
      axis. A value of 1 causes rounding to the nearest tenth of a unit. 
      Negative values are allowed. A value of -1 causes rounding to the nearest 
      10.
      
      The precision can be a floating point number. This can be used to snap all 
      coordinates to an arbitrary grid. The formula used to do the rounding is:
      
         factor = pow(10.0,<precision>)
         newCoordValue = factor * (RoundToInt(oldCoordValue/factor))
      
      So if precision is set to the log10(2) = 0.3010299956639812, all 
      coordinates are rounded to the nearest 1/2 unit.
      
      Similarly, if precision is set to log10(0.5) = 0.3010299956639812, all 
      coordinates are rounded to the nearest even unit.
   
      Range: Real Number   
      
   <y_precision>  
   
      Similar to the precision parameter, this controls the number of decimal 
      places of precision to which the coordinates are rounded for the y axis. 
      This is only applicable if the axis parameter is set to xyz.
   
      Range: Real Number   
      
   <z_precision>  
   
      Similar to the precision parameter, this controls the number of decimal 
      places of precision to which the coordinates are rounded for the z axis. 
      This is only applicable if the axis parameter is set to xyz.

      Range: Real Number   
      
Description

   This function rounds off the coordinates of the passed axis to the passed-in 
   precision. It may be used to remove superfluous decimal points in the 
   coordinates when they are destined for an ASCII output file.

   Any consecutive points that become duplicates as a result of the rounding are 
   thinned by removing the redundant points.
