What Should I Change The Formula In Javascript?

I am developing a speed reading simulation using HTML5 and JS. But, i could not understand client expectation. I have used the below for the app. OR http://jsfiddle.net/Darious/d

Solution 1:

The only thing i can figure out is this :

boldWords = boldWords < 1 ? 1 : Math.floor(boldWords);

returns 1 in the case described (where boldWords begins as ~1.67) , but geussing from your client's wishes, he expects an outcome of 2. Simply change it to

boldWords = boldWords < 1 ? 1 : Math.round(boldWords);

(or use Math.ceil, don't know about any further requirements, and if that would fit them)
