I've been using F# recently and tried to code in a functional way rather than doing OOP all over again in a different syntax. I've now run into a problem that I could solve with a mix of inheritance and discriminated unions but for which I'm trying to find a pure functional style representation. What I want to model is something like th...

It does not look very good for me to always repeat a line-long tuple definition every time I need it. Can I just name it and use as a type name? Would be nice to name its fields also instead of using ._1, ._2 etc. ...
What's the least (negative) integer value that can be exactly represented by Double type in all major x86 systems? Especially in (simultaneously) JVM, MySQL, MS SQL Server, .Net, PHP, Python and JavaScript (whatever corresponding type it uses).

Will be queried on like such: SELECT ... WHERE ... = 'abcd'; SELECT ... WHERE ... LIKE 'ab...
