code: function cents (from, to, decimals) {
    var dec = decimals ? Math.pow(10, decimals) : 100
    var fromFq = toFreq(from)
    var toFq = toFreq(to)
    return Math.floor(1200 * (Math.log(toFq / fromFq) * dec / Math.log(2))) / dec

docs: Get the distance in cents between pitches or frequencies
  
  @param {String|Integer} from - first pitch or frequency
  @param {String|Integer} to - other pitch or frequency
  @param {Integer} decimals - the decimal precision (2 by default)
  @return {Integer} the distance in cents
  
  @example
  cents(440, 444) // => 15.66
  cents('A4', 444) // => 15.66
  cents('A4', 'A#4') // => 100
