How to convert binary fraction to decimal

Question

Javascript has the function parseInt() which can help convert integer in a binary form into its decimal equivalent:

parseInt(\"101\", 2) // 5
         


        

Answer 1

My logic behind is parseInt(res[0] + res[1], base) / Math.pow(base, res[1].length);

Ex : var fValue = '-1100.0011'; var result= parseInt('-11000011', base) / Math.pow(base, '0011'.length);
