Computation of integer logarithms and their remainders for objects of class vli.
Functions log
, log10
and loge
return respectively the integer generalized logarithm, the integer base-10 logarithm and the integer natural logarithm of the given values. Functions logrem
and log10rem
returns the corresponding remainder.
