How to convert int to string on Arduino? Ask Question 76. 9. This sketch is compiled to 1,082 bytes of code using avr-gcc which bundled with Arduino v1. 0. 5 (size of int2str function itself is 594 bytes). Compared with solution using String object which compiled into 2,398 bytes, this implementation can reduce your code size by 1. 2 Kb

Keeping floating point precision when converting from a string? (self. arduino) method, as well as another function for converting strings to floats and they both deliver this same result. Is there a way to convert strings to floats and retain their decimal precision out to say 4-5 decimal points? Im using the Arduino Yun, so if trying

In that case, the round function rounds to the nearest number with N significant digits. The default value is 'decimals', so that round(X,N,'decimals') is equivalent to round(X,N). Example: round(3132,2,'significant') returns 3100, which is the closest number to 3132 that has 2 significant digits.
