Javascript Rounding Off For Positive & Negative Values?

I am trying to build a function that can return correct rounding off for both positive and negative values.

Here is my requirement

Input       Output
-1.8550     -1.86
1.8550       1.86
-1384.8540   -1384.85
1384.8540     1384.85
-1384.8550   -1384.86
-1384.8560   -1384.86
-3203.8640   -3203.86

I tried below, but its not working.!

var customRoundOff = function(value) {
  debugger;
  var valueSign = Math.sign(value);
  var numericalPart = Math.abs(Number((value + "").split(".")[0]));
  var decPart = (value + "").split(".")[1];

  if (decPart && numericalPart) {
    var pntedDecimal = Number('0.' + decPart);
    var roundedDecimal = pntedDecimal.toFixed(2);
    var roundedValue = numericalPart + roundedDecimal;
    
    console.log("pntedDecimal", pntedDecimal);
    console.log("roundedDecimal", roundedDecimal);
    console.log("numericalPart", numericalPart);
    console.log("roundedValue", roundedValue);
    
    return roundedValue * valueSign; // Returns float
  } else {
    return value.toFixed(2); // Returns string
  }
}

customRoundOff(-1.8550);
