Converting int into char array.

Projects Programming
6

I am very new to all this but found that there are functions in the core library's that will 'format' a number and make a string.
Since strings are arrays, using dtostrf (DoubleToString formatted) you can go from 123.456 to [1],[2],[3],- ,[4],[6],[\0] in 1 step.

void TestCode(){
  float iVarToCast = 123.456;
  char buffer[7];
  dtostrf(iVarToCast, 7, 0, buffer);
  lcd.print(buffer);
}

dtostrf(YourNumber, TotalStringLength, NumberOfDecimals, TheTargetArray)
TotalStringLength > Must include all characters the '.' and the null terminator
NumberOfDecimals > The output is rounded .456 become .46 at 2 decimals
TheTargetArray > I suspect 'char strBuffer[]' will work with out a preceding definition but I haven't tried yet

Hope this helps
