Hello Guys! I have this code: /*! * @file basicRead.ino * @brief Output readings of red light and IR * - Pastebin.com

But after i add this:

1. AC = redMax - redMin;

2. DC = redMax - AC;

3. Perfusionsindex = (DC / AC) * 100;

I get this error:

" R=1061 Max=1066
 Min=0
 AC=1066
 DC=0
 Perfusionsindex=0

Any ideas?

it says IntegerDivideByZero. so AC is zero

Post code to this forum! Never use temporary storage sites as pastebin.com because if someone finds this thread in half a year that content is gone and (s)he won't understand what the problem was..

Although the printed values might get the impression that there isn't a division by zero, that impression is wrong. That's because the code prints out the values before it mangles them. After printing out the values AC is calculated to be 0 so you get that error (a division by zero isn't allowed mathematically). Most probably your formula is wrong.
