果尝试使用sprintf()函数在arduino上进行对float指转换为一个字符串的话,你会发现,it doesn't work。弄了很久,还以为是没学c++的原因。其实在arduino上,这个函数就是不对float起作用。 替代的方法是使 …

Arduino Playground - Datatypes

When is it necessary to use “float” instead of “int”? IMHO in Arduino world it is never necessary to use float; well unless you want to do something very fancy like building a space ship route calculation with Arduino. In which case you will have someone on your team who understands the problem in full detail who can decide it is better

In an Arduino program I'm working on the GPS sends the coordinates to the arduino through USB. Because of this, the incoming coordinates are stored as Strings. Is there any way to convert the GPS coordinates to a float or int?

Converting Integer to Byte : arduino - reddit

The int size varies from board to board. On the Arduino Due, for example, an int stores a 32-bit (4-byte) value. This yields a range of -2,147,483,648 to 2,147,483,647 (minimum value of -2^31 and a maximum value of (2^31) - 1). Example int counter = 32 ;// declaration of variable with type int and initialize it with 32 Unsigned int

String To Float conversion in Arduino - Stack Overflow

Floats have only 6-7 decimal digits of precision. That means the total number of digits, not the number to the right of the decimal point. Unlike other platforms, where you can get more precision by using a double (e. g. up to 15 digits), on the Arduino, double is the same size as float.

Displaying FLOAT variables in Arduino. It seems that the Arduino software doesn't have much support for displaying float variables, certainly the sprintf() function doesn't work. However there is a useful c function called dtostrf() which will convert a float to a char array so it can then be printed easily.
