Hi..

How can Serial.print a number being decimal, but without a "." or ","

Example: I receive "1", before Serial.print i need to divide by 5 = 0.2, but i want to Serial.print like 02..
I tried several types of variables, but cant get what i want.

Another question is how to join two variables:
variable a "1"
variable b "2"
ab=12

Thanks

not 100% robust but should get you started. The trick is to isolate single digits..

float x = 1;

x = x/5;

int whole = (int)x;
inf fract = (x-whole)*10;
Serial.print(whole); 
Serial.print(fract);
