Well I want to make this code to show on my LCD a number in x.xxx format alas whatever I try I still get this.

for "0" i get "0.0000000000"
when I increment(using the encoder turning it right) I expect to get
0.262 but I get "0.2619999884"
when I rotatate again I should get
0.524 but I get "0.5239999771"
0.786 i get "0.7860000133"
and so on
I want to get numbers like:
0.262
1.310
1.834
2.620
an so on so pls help :-/

a number in x.xxx format

#include <LiquidCrystal.h>

LiquidCrystal lcd (7,6,5,4,3,2); // Or whatever...

void setup()
{
    lcd.begin(16,2);
    lcd.clear();
    float Pi = 3.1415926;

    // Show five decimal places on the first row   
    lcd.setCursor(0,0);
    lcd.print("Pi = ");
    lcd.print(Pi, 5);

    // Show three decimal places on the second row
    lcd.setCursor(0,1);
    lcd.print("Pi = ");
    lcd.print(Pi, 3);

}

void loop()
{
}

Output on LCD:


Pi = 3.14159
Pi = 3.142

Regards,

Dave

Doesn't work that way, man
I need to get exactly 0.262 no some proxy number or rounding it.
When I continue to increment(to rotate the encoder)because of the rounding and the difference between 0.262 and that strange number "0.2619999884" will lead to mathematical mistake
After all I multiply the incrementation with that "0.2619999884"

Why the hell is that I declare the number as 0.262 and I get this s*&t
"0.2619999884"

Need another solutin

I need...exactly...

First of all, your stated requirements were to find a way to "show x.xxx number on the LCD" I demonstrated a way to do that.

Now...

Nasty reality with floating point numbers: "Exactly" may not be possible.

The decimal number 0.262 is not exactly representable as a binary floating point number. The compiler does the best it can to store a value as close as it can to the one you specify. See Footnote.

Even if you happen to pick a number that is exactly representable in your computer, as soon as you perform some arithmetic (like adding decimal 0.1, for example) the result may not be exactly representable.
Reference: Floating-point arithmetic - Wikipedia

Bottom line: If your C or C++ program needs exact representation of decimal floating point numbers you may have to create your own class (or find one on the web) that operates with decimal arithmetic on numbers stored in some decimal format. Built-in Arduino (C and C++) floating point numbers and their operators are binary.

One other possibility (but I won't try to determine whether it applies to your requirements):
Sometimes it is possible to transform the problem to use only integer arithmetic. If people require exact values for three decimal place numbers, sometimes they find that it is possible to multiply everything by 1000 and use integer arithmetic in all of the calculations. Stuff like that.

Regards,

Dave

Footnote:
In my experience (including four years as a US Navy enlisted man about 50 years ago---or was it longer?), I got pretty good at cursing, but I found that cursing at a compiler (or at any other part of the universe) doesn't change fundamental facts.

Well this is how I made it I get a mathematical mistake of 0.001 at the maximum encoder position of 65535 which is prette darn good for me.

P.S.
WOOOOW, you are some pretty old fart ;D

Just remember the wise are often old farts, because wise is another name for experienced and old farts have a lot of it. :slight_smile:

Another old Navy man on the opposite side of the pond, not quite 50 but 30 years ago......

The old fart appreciation society.

Us old farts designed and implemented the new easy world you young punks often take advantage of. ;D

Without us old farts, there would be no microcontrollers. :sunglasses:
