   Jan 28, 2018 · Hello, I am all new to Arduino and C++ and trying to learn/understand it. It was 25+ years ago I did some programming in a non high level scripting language. Only playing with Python for the last 10 years. So I have been reading up on the difference between #define and const on the forum. For exampel these two questions: The difference between #define and const #define versus const and other software performance issues My first Arduino project is building some sensors with the MySensors pr...

   Mar 17, 2019 · Hi friends! Maybe the next question is very basic, but I don't understand deeply the meaning of variable "float". If you search the definition of variable float in webpage of Arduino: float - Arduino Reference you can see the next: "(..) Floating point numbers are not exact, and may yield strange results when compared. For example 6.0 / 3.0 may not equal 2.0. You should instead check that the absolute value of the difference between the numbers is less than some small number." I don't unders...

   Jan 18, 2024 · No, not with any normal computer. A float can represent a number with 6 to 7 total digits of accuracy. It is not possible to represent the exact value of all numbers with a given number of decimal places. For example, 0.1 cannot be represented exactly by a float value. I suspect that your example of 20.09 cannot be represented exactly, either.
