Why was Fortran created?
Pages: 12
I read it was created to do high end math stuff with ease but given the right libraries can't C++ do that stuff with just as much ease?

To be a bit less condescending:
Fortran -> 1957
ANSI C -> 1972
C++ appeared in 1983
People still use Fortran because there's a metric ton of code that is written in it and it's more cost-effective to just maintain instead of rewriting it, Fortran compilers have also had substantially more time to develop robust optimizations. For *pure* number crunching, you can't really beat Fortran (except for maybe straight-up ASM, but writing in Fortran is more portable).

| OK, so you think that time flows that way, do you? Interesting. |
You say that like time is linear. :'D
Nope, a "directed" acyclic graph.
The direction depends on the sign of the charge of the electron.

Wouldn't "graph" imply that time has discrete states? (a finite number too, but let's not be too picky here). I don't think it works that way.
Time isn't necessarily continuous. Just because the graph would be continuously increasing doesn't mean it's not finite (the Big Bang was a clear starting point; we've had a topic on the possible ending points too).
Fortran was the first compiled language (I think).
It's an abbreviation of "Formula Translation".
The compiler translated high-level formulas into low-level code.
Back in the day, this was a revolutionary concept.

@science man: Um, no? f(t) is the function of time, and ? is the limit as f(t) approaches 0...from both sides >:)
Now you just need to actually define the function (there's not just one function of time :O) and define the 0 point (epoch, the death of ludwig XIV, the last time you ate a cheeseburger?).

Thanks for explaining that. I didn't know.
@I.B.
I knew you meant by time. I should've said f(t)=the equation of life in the sense of time. Although you are right, I did mess up by saying ?=.

Actually, according to Wikipedia, the first ever compiled language was A-0 (developed by Grace Murray Hopper)
But FORTRAN was purportedly the first complete one.

PS They didn't even let Grace retire!!!
That means I've still got more than 50% of my working life ahead of me! 8-0

They say time is a human creation, no other species recognizes time. Just day and night, and the four seasons. Does this mean time starts and ends with human life? Or does it just cease to be recognized?
Hardly so. If it didn't exist before we started measuring it, we couldn't have devised a method for measuring it.
