  /**
   * Create a number or convert a string, boolean, or unit to a number.
   * When value is a matrix, all elements will be converted to number.
   *
   * Syntax:
   *
   *    math.number(value)
   *    math.number(unit, valuelessUnit)
   *
   * Examples:
   *
   *    math.number(2)                         // returns number 2
   *    math.number('7.2')                     // returns number 7.2
   *    math.number(true)                      // returns number 1
   *    math.number([true, false, true, true]) // returns [1, 0, 1, 1]
   *    math.number(math.unit('52cm'), 'm')    // returns 0.52
   *
   * See also:
   *
   *    bignumber, boolean, complex, index, matrix, string, unit
   *
   * @param {string | number | BigNumber | Fraction | boolean | Array | Matrix | Unit | null} [value]  Value to be converted
   * @param {Unit | string} [valuelessUnit] A valueless unit, used to convert a unit to a number
   * @return {number | Array | Matrix} The created number
