convert

A little bit of C++ that I whipped up to convert to and from binary, since I didn't find anything too inspiring online:

string binary(int v, int bits) {

  int p;

  string s = "";

  for (int i = bits; i >= 0; i--) {
    p = pow(2,i);
    if (v & (1 << i)) {
      s += "1";
    } else {
      s += "0";
    }
  }

  return s;
}

Convert a bitstream to a floating point number between 0 and 1. It's a smart little function
because it figures out the range from the length of the input string

float convert_bitstring_to_float(string s) {

  float v = 0;

  int len = s.length();

  for (int i = 0; i < len; i++) {
    cout << "i=" << i << " s[i]=" << s[i] << endl;
    if (s[len-i-1] == '1') {
      v += (1 << i);
    }
  }  
   
  return v / (pow(2,len));
}
