  /**
   * 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`
