+   * Test whether a value is an numeric value.
+   *
+   * The function is evaluated element-wise in case of Array or Matrix input.
+   *
+   * Syntax:
+   *
+   *     math.isNumeric(x)
+   *
+   * Examples:
+   *
+   *    math.isNumeric(2)                     // returns true
+   *    math.isNumeric('2')                   // returns false
+   *    math.hasNumericValue('2')             // returns true
+   *    math.isNumeric(0)                     // returns true
+   *    math.isNumeric(math.bignumber('42'))  // returns true
+   *    math.isNumeric(math.bigint('42'))     // returns true
+   *    math.isNumeric(math.fraction(4))      // returns true
+   *    math.isNumeric(math.complex('2-4i'))  // returns false
+   *    math.isNumeric([2.3, 'foo', false])   // returns [true, false, true]
+   *
+   * See also:
+   *
+   *    isZero, isPositive, isNegative, isInteger, hasNumericValue
+   *
+   * @param {*} x       Value to be tested
+   * @return {boolean}  Returns true when `x` is a `number`, `BigNumber`,
+   *                    `Fraction`, or `boolean`. Returns false for other types.
+   *                    Throws an error in case of unknown types.
