What is the difference between the following codes?
code1
var=2**2*3
code2
var2=2*2*3
I see no difference. This raises the following question.
Why is the code1 used if we can use code2?

2**2 = 2 power-of 2
2*2 = 2 times....
Change the numbers and you'll see a difference.
So "2 times 2" and "2 to the power 2" are the same.
Double stars ( ** ) are exponentiation.

In mathematics the identity (1 + sqrt(2))^2 = 3 + 2*sqrt(2) holds true. But in floating point (IEEE 754, using single precision i.e. 32 bits) calculations it's not the case, as sqrt(2) doesn't have an exact representation in binary.
So does using a approximated...

To answer another part of your question....
So does using a approximated value of sqrt(2) provide with numbers that require decimal fractions (other than powers of .5 and .2) to represent.
To the exact result of a computation are expected.

What's an elegant way to unify X,Y with (1,2), (1,-2), (-1,2), (-1,-2), (2,1), (2,-1) , (-2,1), (-2,-1)?
Doing it this way seems error prone and tedious:
foo(1,2). foo(1,-2). foo(-1,-2). ... ... ...
And this way seems too expensive:
foo(X,Y) :- L = [1...

Foo(X.
Foo(X, Y) :- foo(-X, Y).
Foo(2, 1).
Foo(1, 2).
Foo(X,Y):- foo0(X,Y); foo0(Y,X).
A further development on what was commented:
generate_pairs_foo(X,Y) :- L = [1,-1,2,-2], member(X,L]), member(Y,[2,-2]).

1) long to wide question:
I have a dataset with 3 columns: person, event, frequency. If the frequency is zero, the row is not in the table. Is there a simple way using basic R functions or libraries to convert this table to wide format, with one row per...

For the first part of your question, you can either use... .
Re: the first part, you can filter out the rows with Frequency == 0 by
filteredRows <- data$Frequency != 0 ## restrict ourselves to looking at the data where Frequency != 0 .
