Description

       The call clog10(z) is equivalent to:

           clog(z)/log(10)

       or equally:

           log10(cabs(c)) + I * carg(c) / log(10)

       The other functions perform the same task for float and longdouble.

       Note that z close to zero will cause an overflow.

History

       glibc 2.1.

       The identifiers are reserved for future use in C99 and C11.

Library

       Math library (libm, -lm)
