Question
Does anyone know of a way to round a float to the nearest 0.05 in JavaScript?

Example

Answer 1

My solution and test:

let round = function(number, precision = 2, rounding = 0.05) {
  let multiply = 1 / rounding;

  return parseFloat((Math.round(number * multiply) / multiply)).toFixed(precision);
};
