Have some ideas how to do it.
int value;//value to be shown on lcd
int value_col; //lcd column where the value will be placed
int cursor_col;//column where the cursor is placed
int value_change; //by this value suppose to be changed 1, 10, 100, ..
value_change= ???
// the expression is:
// value_change=10^((value_col-cursor_col)+(lg value)+1)
//
value+=value_change;
How to write expressions like: in power of, or logarithm ?
