Number() vs parseInt() vs plus vs bitwise (v74)

Revision 74 of this benchmark created by Salvo on

Setup

function CalcClass() {}
    
    CalcClass.prototype.parseNumber = function(str) {
      return Number(str);
    };
    
    CalcClass.prototype.parseToInt = function(str) {
      return parseInt(str);
    };
    
    CalcClass.prototype.parsePlus = function(str) {
      return +str;
    };
    
    CalcClass.prototype.parseBitwise = function(str) {
      return str >> 0;
    };
    
    CalcClass.prototype.parseMultiply = function(str) {
      return str * 1;
    };
    
    
    CalcClass.prototype.parseBitwiseNot = function(str) {
      return~~ str;
    };
    
    CalcClass.prototype.parseToIntBase10 = function(str) {
      return parseInt(str, 10);
    };
    
    CalcClass.prototype.parseBitwiseOr = function(str) {
      return str | 0;
    };
    
    CalcClass.prototype.parseMinus = function(str) {
      return str - 0;
    };
    
    var calc = new CalcClass();
