14/07/2010 "Remember that a floating-point number can only approximate a decimal number, and that the precision of a floating-point number determines how accurately that number approximates a decimal number. By default, a Double value contains 15 decimal digits of precision, although a maximum of 17 digits is maintained internally."... There is a function in the standard Arduino library called dtostrf(). I think of it as "Decimal to String Float". You pass in the float, how wide you want the whole number to be (if it will fit), the number of decimals of precision - and the buffer you want it to fill.

14/05/2015 Recoding variable type (string to float) for date 14 May 2015, 10:39 . I have two datasets I would like to merge (using joinby). The variables I would like to merge the datasets by are an entity identifier (float variable) and a date indicating quarter and year (also float).

  • If you know how long the float is, create a char array of the length of the string. Add 0 to arr[0] and . to arr[1]. Set int I to 2. Multiply by 10 and floor it (call this temp).
  • Add comment Show 2. 10 Can be a number between roughly 1.5 x 10^45 to 3.4 10^38, in floating point format. String: A sequence of characters (eg, "Hello User 6555") (no specified maximum length, as far as I'm aware!) boolean: A true/false value. Can only contain either the value true or false. There are many more types that you can use for variables, including other numeric types for
  • Finds whether the type of the given variable is float. Note: To test if a variable is a number or a numeric string (such as form input, which is always a string), you must use is_numeric().
  • Declaring a variable means defining its type, and optionally, setting an initial value (initializing the variable). Variables do not have to be initialized (assigned a value)
