Close. I just got the scoop from Nuuj: Lingo looks at the line of code, sees that it's a math operation and then decides what the resulting data type will be. If all arguments are integers then the result will be an integer, if not then the result will be a float. In the case cited, neither argument is an integer (they're both strings) and therefore the resulting data type is a float and so Director then tries to convert the type of each argument to a float (please see my PS about converting strings to floats), in doing so "27935" becomes 27935.0 and "5500" becomes 5500.0, then the addition is performed add should return the correct result. The above is true no matter what data type you pass into the equation: x = FALSE + 1 -- first FALSE is converted to an integer x = 0 + 1 -- both args are ints, no conversion needed so put x -- x = 2 y = TRUE + 5.0 -- first TRUE is converted to an integer y = 1 + 5.0 -- both args are not integers, convert each to a float y = 1.0 + 5.0 -- do the math now... put y -- 6.0000 z = "3" + "5" -- neither are integers, convert them to floats z = 3.0 + 5.0 -- do the math put z -- 8.0000 w = "3.0" * 14 -- both args are not integers, convert each to a float w = 3.0 * 14.0 -- do the math put w -- 42.000 I figure that's enough to get the point across, if not then give a holler. Cheers, Tom P.S. When type converting strings in this fashion be careful of things like this: test = "1 + 4" * 3 This will *not* work as the string is parsed to see if it's a number, as soon as the space is found that fails. It would be more optimal to have Lingo _value_ the string found instead of parse it, but it doesn't, sorry.
