arduino printf float code example

Example: arduino sprintf float

// On arduino, sprintf does not support formatting floats, but it can be done 
// with some simple integer formatting:
// (Only works for positive numbers)

float f = 3.14;
sprintf(str, "Float value: %d.%02d", (int)f, (int)(f*100)%100);

// str will now be: "Float value: 3.14"
