+.SH DESCRIPTION
+The call
+.I clog10(z)
+is equivalent to:
+.PP
+.in +4n
+.EX
+clog(z)/log(10)

+or equally:
+.PP
+.in +4n
+.EX
+log10(cabs(c)) + I * carg(c) / log(10)
+.EE
+.in
+.PP
+The other functions perform the same task for
+.I float
+and
+.IR "long double" .
+.PP
+Note that
+.I z
+close to zero will cause an overflow.
