Erdös-Borwein constant
The Erdős-Borwein constant is the sum of the reciprocals of the Mersenne numbers.
By definition it is:
It can be proved that the following forms are equivalent to the former:
where  represents a multiplicative function, the number of positive divisors of the number  .
Paul Erdős showed that the constant E is an irrational number.
