Subject: convert binary array to floating point decimal

new to ruby here, looking for a little help

I'm trying to convert some C# code to ruby, however I'm not getting the
desired results
The code is supposed to convert a binary string to a floating point
number

public float binaryStringToFloat(int length)
{
   float result = 0;
   int num = 0;
   // form the integer number from the binary string
   for (int i = 0; i < length; i++)
      {
      num = num << 1;
      num = num + binaryArray[(length - i) - 1];
      }
   // scale to the floating point value
   result = (float)num;
   result = result / (1 << binaryArray.length/2);
   return result;
}

any help will be appreciated
