     22    * Unary plus operation.
     23    * Boolean values and strings will be converted to a number, numeric values will be returned as is.
     24    *
     25    * For matrices, the function is evaluated element wise.
     26    *
     27    * Syntax:
     28    *
     29    *    math.unaryPlus(x)
     30    *
     31    * Examples:
     32    *
     33    *    math.unaryPlus(3.5)      // returns 3.5
     34    *    math.unaryPlus(1)     // returns 1
     35    *
     36    * See also:
     37    *
     38    *    unaryMinus, add, subtract
     39    *
     40    * @param  {number | BigNumber | Fraction | string | Complex | Unit | Array | Matrix} x
     41    *            Input value
     42    * @return {number | BigNumber | Fraction | Complex | Unit | Array | Matrix}
     43    *            Returns the input value when numeric, converts to a number when input is non-numeric.
