//
//Round function
//
//This function is used to round float value by decimal point
//

//Syntax  
  rnum=round(value,nn);
//argument 1 is target value to be rounded.
//argument 2 is figure. plus  value is decimal figure over 1.0
//                      zero  value is decimal figure at 0
//                      minus value is decimal points figure under 1.0.

//
//Example
//
round(356.25,0)  -> 365
round(365.25,-1) -> 365.3
round(365.25,1)  -> 370          


//Example 2
//three figure random integer generates by 100 times loop.
