### Square Root & Log Calculator

##### 1. Square Root
Need a square root? Here is a simple solution. Since all signals are integers, there is just some rounding error. Just follow this instructions:

Input value must be set as signal I (placed in constant combinator). There also must be signal O set as 1 (it is important to keep this value constantly on 1). And then, just read the result from a green network as signal O

Description:
1. comb: I / O -> O
2. comb: O + 0 -> O
3. comb: O / 2 -> O

##### 2. Log
Need a Log? Here is it (this one is little bit larger)

It works in a similar way - I signal is input, B signal is base of the logarithm and O signal is output.

I know I'm a bit late to the party, but this is magnificently simple, and just what I needed. Lovely!
