Arduino round
It is a very bad idea to use float. That being said. multiply by 2 and do a standard round. Then divide back by 2. For example: 1.34 *2 = 2.68 round(2.68) = 3 3 /2 ... , float x = 2.9; int y = round(x); // 3. Floating point math is also much slower than integer math in performing calculations, so should be avoided if, ...,I need to round a number .. there is no function in reference to do that. ... Maybe like these: abs, floor, int, mround (returns a number rounded to ... ,round function to work. #include <Math.h> void setup() Serial.begin(9600); } void loop() ,There is a round(), by the way, but it only rounds to the nearest integer, not to a set number of decimal places. GoForSmoke. , The macro round() in "Arduino.h" is a bug. It can not handle large floating point numbers and it returns a long integer. #define round(x) (( ...,What I would like to do now is to round the respective second values to the nearest .5 or .0. How would I go about that in my code? ,I want to round up the answer to its closest "whole number", i understand that i can make a long If statement but are hoping there is a easier way. , As far as I know, the Serial.print (or println) does rounding up and down. All you have to do is take a float variable and do Serial.print( value, 1);.
