How to sprintf a float with Arduino - Yet Another Arduino Blog

2/29/2017Float and double are the same on AVRs - they aren't on the Due and some other fancier microcontrollers, but they are for AVRs. A common practice is to do all the math as integers, and only at the end, display that as a decimal - for example if you want 3 decimal places, do all your math as integers a factor of 1000 higher, then divide by 1000. 0 at the end (or if printing, print number/1000

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. The format is

p() function equation wrong arduino

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.

Read float and long from external EEPROM chip. It works great for int and char values but I also need to read short, long, and float values. They are stored in this order: 1510543923 is stored as: 01011010 00001001 00010010 00110011. But on your Arduino an int is 16-bits long, thus by shifting it 16 positions you are dropping off all of
