# Series, and Floors, and Numbers Oh My!!!!

Algebra Level 5

A number Z is equal to $$\frac { P }{ Q }$$

Where P is equal to the floor of 1000 times S, where S is:

$$\displaystyle\sum _{ n=1 }^{ 100 }{ \frac { 1 }{ n } } = S$$

$$\left\lfloor 1000S \right\rfloor = P$$

And Q is defined as the smallest positive integer solution to the equation:

$${ a }^{ 3 }+{ b }^{ 3 }={ c }^{ 3 }+{ d }^{ 3 } = Q$$

Where a,b,c, and d are positive distinct integers;

Then find Z, where:

$$\frac { P }{ Q } = Z$$

Details and Assumptions:

You may use a calculator if you wish, but you may not use Wolfram Alpha.

Good Luck!
