What is the standard (or best supported) big number (arbitrary precision) library for Lua?
(6 answers)
Closed 8 years ago.
As an example, I want to convert:
1j16qd5g0lc
To:
5589146303201280
But currently ‘tonumber’ converts it to:
5.5891463032013e+15
I understand that there is a bit.tonumber function that might work better but that function is not available to me. Could someone implement what I need easily? I am not too familiar Lua.
Thank you! :)
Try print(string.format("%.0f",tonumber("1j16qd5g0lc",36))).

Is there any way I can define a variable in LaTeX?

Closed 5 years ago.
Is there a way to add a text by reference using LaTeX? I have several text references to 'versionXX.yy'. I wonder if I can define this in one place so I don't need to update it in all places.
Thanks
You could define a variable or new command with your version at the beginning and then just use this definition. See here
Btw. there is a special site called tex.stackexchange.com for this kind of questions.

how to create tcl proc with hyphen flag arguments
(4 answers)
Closed 7 years ago.
I have a script that will require many short and long options and was wondering what would be the most efficient way to parse the command line arguments. Using for-each and if-else would make the code too long and difficult to modify, so is there be any standard function that can help me (something like getopt for C)?
We discussed this four days ago and a few suggestions were posted.
There is also the cmdline package in Tcllib.

What is the difference between '->' (arrow operator) and '.' (dot operator) in Objective-C?
(3 answers)
Closed 8 years ago.
I am familiar in iOS/Objective C. Now I see people using self->property in some cases. How does it differ from self.property? What is the actual need? I googled, no answer. Curious in it.
self->property is the same as _property, meaning it accesses the ivar directly.
self.property on the other hand calls the setter/getter.
