Hello, my problem is that i am not able to format correctly a string. I'm using serial communication and before send a string i need the integer to have 3 digit always if it is a 1 digit i need it to have zeros to the left so it makes 001 or for example 27 comes 027. I use a control to get a number between 0 and 400, then i pass this number through a Number to Decimal String block and then I connect it to a format into string block. I can't find the correct format specifier to get the result i want. I add an image of my block diagram.
