Limited harmony series

[Noorolhoda]

Hi
I need to solve a limited harmony series like this:
∑1/i

Sigma is limited between a and b which both of them are very big numbers:
Example: a=60e+10, b=60e+15

How could I solve it? Approax answer is ok too.

I have no special knowledge of this, but since what you want is the difference between two harmonic numbers (sums of finite harmonic series), you might be able to get a satisfactory approximation using the formulas here: https://en.wikipedia.org/wiki/Harmonic_number#Calculation
