How can I duplicate a random number in two places on the same page in a latex editor?
2
I am trying to create a mental math practice sheet generator in a latex editor. For the number of questions intended, I require only half of A4 sheet. So the other half I want to print the same set of questions for another student.
In excel we can simply copy the values of a cell into another to duplicate. How do I duplicate all the questions containing randomly generated numbers.
I have the syntax for the questions. Just need help with duplicating part. Thanks.
tikzset{declare function={randomfixed(a,b) = int(random(0,int(b-a))+a);}}
% get random integer
newcommandrandomint[2]{bgroup%
pgfmathsetmacromyval{randomfixed(#1,#2)}%
pgfmathsetmacrofinal{(myval < 0)?"(myval)":myval}%
finalegroup%
}
newcommand{randnzi}{%random non-zero integer, change random (argument) to increase or decreases range
pgfmathsetmacro{a}{int(ifthenelse(rand > 0, 1, -1)*random(1,9))}%
}
% get random integer for equation - the only diff from randomint is that this one doesn't generate () for negative numbers
newcommandrandomeqint[2]{bgroup%
pgfmathsetmacromyval{randomfixed(#1,#2)}%
pgfmathsetmacrofinal{(myval < 0)?"myval":myval}%

save the random number in a macro, or rather set the random seed identically (now that I see it is a whole series you want replicated)

Thanks for the answer @jfbu but I am fairly new to latex. Don't know macro too well. If you could provide me with easy resource to read on macro, I would be very grateful. Thanks.

"macro" is a generic name, LaTeX "commands" are macros. But what you are lacking is knowledge ofletoredefwhich are not described usually in LaTeX books. But this is what is needed here simply to store once and for all a given random seed in a "macro" and use it after, see my answer.

It would be easier if you had provided a usable test file but if I understand your question you could replace
foreach n in {1,...,5}{
$randomint{-10}{10} randomop{} randomint{-10}{10} = $par
%par is used in for loop to create a linebreak after each iteration
}
by
sbox0{$randomint{-10}{10} randomop{} randomint{-10}{10} = $}
foreach n in {1,...,5}{
usebox{0}par
%par is used in for loop to create a linebreak after each iteration
}
To get 5 identical copies.
As jfbu has provided a test file here is the same technique but this time boxing the entire list and re-using. here I used a parbox of width textwidth for a vertical repetition, you could make the parbox narrower and lay out horizontal copies.
documentclass{article}
usepackage{tikz}
tikzset{declare function={randomfixed(a,b) = int(random(0,int(b-a))+a);}}
% get random integer
newcommandrandomint[2]{bgroup%
pgfmathsetmacromyval{randomfixed(#1,#2)}%
pgfmathsetmacrofinal{(myval < 0)?"(myval)":myval}%

}
newcommand{randnzi}{%random non-zero integer, change random (argument) to increase or decreases range
pgfmathsetmacro{a}{int(ifthenelse(rand > 0, 1, -1)*random(1,9))}%

Jan 14 at 16:02
@jfbu I had trouble understanding the question, but anyway the basic technique of putting the random text in a box and re-using the box answers the question even if I duplicated the wrong text. But I'll delete if it's definitely the wrong answer, OP to confirm...

In such cases don't moderators automatically hand over a share of your reps to @jfbu ?

Jan 14 at 16:07
Thanks @DavidCarlisle for the effort but you are duplicating a random number 5 times one after another. That solves the problem in strict technical sense. But it does not help in obtaining the duplicate of a random number(s) many lines down the page. Think like this: I need to store the random number in a variable & print the variable in any two different places on the page. And many different variables containing different random numbers are to be printed in different places like a linear equation or algebraic expressions. But two of each question in a single A4 page on either half.

Jan 14 at 16:58
@rhlchd you can use as many boxes as you like and display the content as often as you need, so you can for example typeset your whole question sheet into a box and then re-use that box multiple times, but as you did not provide a test file just a large but unusable code fragment it wasn't clear to me exactly what you wanted to duplicate.

Thanks @DavidCarlisle for the effort but you are duplicating a random number 5 times one after another. That solves the problem in strict technical sense. But it does not help in obtaining the duplicate of a random number(s) many lines down the page. Think like this: I need to store the random number in a variable & print the variable in any two different places on the page. And many different variables containing different random numbers are to be printed in different places like a linear equation or algebraic expressions. But two of each question in a single A4 page on either half.

@rhlchd you can use as many boxes as you like and display the content as often as you need, so you can for example typeset your whole question sheet into a box and then re-use that box multiple times, but as you did not provide a test file just a large but unusable code fragment it wasn't clear to me exactly what you wanted to duplicate.

It would be easier if you had provided a usable test file but if I understand your question you could replace
foreach n in {1,...,5}{
$randomint{-10}{10} randomop{} randomint{-10}{10} = $par
%par is used in for loop to create a linebreak after each iteration
}
by
sbox0{$randomint{-10}{10} randomop{} randomint{-10}{10} = $}
foreach n in {1,...,5}{
usebox{0}par
%par is used in for loop to create a linebreak after each iteration
}
To get 5 identical copies.
As jfbu has provided a test file here is the same technique but this time boxing the entire list and re-using. here I used a parbox of width textwidth for a vertical repetition, you could make the parbox narrower and lay out horizontal copies.

save the random number in a macro, or rather set the random seed identically (now that I see it is a whole series you want replicated)

Thanks for the answer @jfbu but I am fairly new to latex. Don't know macro too well. If you could provide me with easy resource to read on macro, I would be very grateful. Thanks.
– rhlchd
Jan 14 at 16:59
"macro" is a generic name, LaTeX "commands" are macros. But what you are lacking is knowledge of
letoredefwhich are not described usually in LaTeX books. But this is what is needed here simply to store once and for all a given random seed in a "macro" and use it after, see my answer.– user4686
