It has been suggested that this article be merged with Logarithm. (Discuss) Proposed since October 2006.

A cologarithm of a number, sometimes shortened to colog, is the logarithm of the multiplicative inverse of the number. This means that

c o log x = log ( 1 x ) = log x . {\displaystyle \mathrm {co} \log x=\log \left({\frac {1}{x}}\right)=-\log x.\,}
