How to avoid scientific notation for large numbers in JavaScript?

Question

JavaScript converts a large INT to scientific notation when the number becomes large. How can I prevent this from happening?

Answer 1

This is what I ended up using to take the value from an input, expanding numbers less than 17digits and converting Exponential numbers to x10^y

// e.g.
//  niceNumber("1.24e+4")   becomes 
// 1.24x10 to the power of 4 [displayed in Superscript]

function niceNumber(num) {
  try{
        var sOut = num.toString();
      if ( sOut.length >=17 || sOut.indexOf("e") > 0){
      sOut=parseFloat(num).toPrecision(5)+"";
      sOut = sOut.replace("e","x10")+"";
      }
      return sOut;

  }
  catch ( e) {
      return num;
  }
}
