Hello guys, I am a little confused about the following. I need to get the number of floating digits of a float number. So I have for example the number: 12.345678 And I know that the number of int digits are 2 with the following code: float a = 12.345678; void setup() { int u=0; while(a/po…

int numb_d(float n){ int nb=0; while(((float)pow(10,nb))*n!=(int) (((float)pow(10,nb))*n)) nb++; return nb; } This method should suffice. It basicly always moves the comma one digit to the left and chops the digits after the comma of. And checks if choppign the digits of made a difference. I hope…
