JS to solve the problem of floating point multiplication precision loss

for example

1.11 * 100 = 111.00000000000001

terms of settlement

export const format = function(f?, digit?) {
    
  //  solve js Loss of accuracy 
  // digit It's to keep a few decimal places 
  const m = Math.pow(10, digit);
  return Math.round(f * m) / m;
};

format(1.11 * 100)
