Say you have a float variable that''s holding a value of 8.6487 and you would like to print that value rounded to the second decimal place(I.e. 8.65), how would you do that? Thanks..

I''ve always like the flexible rounder, one that let''s you pick the precision.

  
#include <math.h>

float round(float num,int place)
{
int power=pow(10,place);
return ((float)((int)(power*num))/(float)power);
}
