Calculate average characters of string
Brainfuck 106 bytes

,[&gt;,&lt;.[-&gt;+&lt;]&gt;&gt;++&lt;[&gt;[-&gt;+&gt;+&lt;&lt;]&gt;[-&lt;&lt;-[&gt;]&gt;&gt;&gt;[&lt;[&gt;&gt;&gt;-&lt;&lt;&lt;[-]]&gt;&gt;]&lt;&lt;]&gt;&gt;&gt;+&lt;&lt;[-&lt;&lt;+&gt;&gt;]&lt;&lt;&lt;]&gt;[-]&gt;&gt;&gt;&gt;[-&lt;&lt;&lt;&lt;&lt;+&gt;&gt;&gt;&gt;&gt;]&lt;&lt;&lt;&lt;&lt;]


This is my first participation in a code-golf, please be gentle!
It does work but brainfuck can't handle floats (not that i know of) so the rounded value is always the bottom one (might fix my algorithm later).

Also, the algorithm averages the values 2 by 2, meaning it could be innacurate in some spots.
And I need to fix a bug that is printing a number at the end of the output too.
