+   * Calculate the 10-base logarithm of a value. This is the same as calculating `log(x, 10)`.
+   *
+   * For matrices, the function is evaluated element wise.
+   *
+   * Syntax:
+   *
+   *    math.log10(x)
+   *
+   * Examples:
+   *
+   *    math.log10(0.00001)            // returns -5
+   *    math.log10(10000)              // returns 4
+   *    math.log(10000) / math.log(10) // returns 4
+   *    math.pow(10, 4)                // returns 10000
+   *
+   * See also:
+   *
+   *    exp, log, log1p, log2
+   *
+   * @param {number | BigNumber | Complex | Array | Matrix} x
+   *            Value for which to calculate the logarithm.
+   * @return {number | BigNumber | Complex | Array | Matrix}
+   *            Returns the 10-base logarithm of `x`
