+   * Unary plus operation.
+   * Boolean values and strings will be converted to a number, numeric values will be returned as is.
+   *
+   * For matrices, the function is evaluated element wise.
+   *
+   * Syntax:
+   *
+   *    math.unaryPlus(x)
+   *
+   * Examples:
+   *
+   *    math.unaryPlus(3.5)      // returns 3.5
+   *    math.unaryPlus(1)     // returns 1
+   *
+   * See also:
+   *
+   *    unaryMinus, add, subtract
+   *
+   * @param  {number | BigNumber | bigint | Fraction | string | Complex | Unit | Array | Matrix} x
+   *            Input value
+   * @return {number | BigNumber | bigint | Fraction | Complex | Unit | Array | Matrix}
+   *            Returns the input value when numeric, converts to a number when input is non-numeric.
