Bug 19673 reports that the documentation of clog10 is incorrect, both
failing to include the division by log (10) in the imaginary part and,
in the non-TeX version of the equation only, describing the LHS as log
rather than log10.
This patch fixes both issues. Note: I think it's appropriate that the
LHS says log10 not clog10, and that the cexp and clog descriptions
referred to in a comment in that bug report similarly say exp and log;
this is a mathematical description not a literal C one.
Tested for x86_64.
[BZ #19673]
* manual/math.texi (Exponents and Logarithms): Correct description
of clog10.

@var{z}. Mathematically, this corresponds to the value
@ifnottex
-@math{log (z) = log10 (cabs (z)) + I * carg (z)}
+@math{log10 (z) = log10 (cabs (z)) + I * carg (z) / log (10)}
@end ifnottex
@tex
-$$\log_{10}(z) = \log_{10}|z| + i \arg z$$
+$$\log_{10}(z) = \log_{10}|z| + i \arg z / \log (10)$$
@end tex
