Problem with lcd representation of float (printf)

[Bomba]

I initialize the LCD
//Initiate LCD
lcd_init();
delay_ms(6);
Later write the paratext
printf(lcd_putc,"\f 33\xDFC Control\nTemp.= 00.00\xDFC");
Then after that whe I read the temp value I refresh only the number
A_Temp=Acumu;
A_Temp*=50;
A_Temp/=1023;
lcd_gotoxy( 8, 2);
printf(lcd_putc,"%2.2f",A_Temp);

But why same time write a number with three character after point instead of two, only sometimes but is very frequent.

Thanks in advance

I have not tested your code on my demo board.
But here is a possible reason for your problem:

If your code sometimes writes

12.34

and then it writes

5.67

the last digit of the previous value could still be present.
So you would see:

5.674

Is this what you are seeing ? Is that your problem ?

If so, one easy solution is to clear all 5 character positions
before you write a new value. You could do this by setting
the X,Y position to the start of the field, and then send 5 space
characters.
