Hi! I'm DragonLord, a grad student studying Computer Science. You might know me as a regular on Super User. I've always loved programming and working with computers, but I also happen to like working with calculators. I'm not a huge calculator programmer, but I enjoy using the latest in calculator technology.

I've gone through several different calculators over the years, starting from a TI-84 Plus in middle school (which still works), to a TI-Nspire in high school (the original Clickpad model), to an HP 50g for AP Calculus, to my current HP Prime. I sold my TI-Nspire a while back, but I still have the others. I absolutely love my Prime—that touchscreen is awesome and it's incredibly fast. A while back, I wrote an article on my personal website about benchmarks of the different calculators I've worked with and the HP Prime was by far the fastest of the calculators I tested.

Anyway, it's nice to be a part of the calculator community. Once again, hello!

Hello there DragonLord, welcome to Omnimaga! Is your name a nod to Dragonlord from Dragon Warrior, or is it from something else? Anyhow, hope you enjoy it here.

No, not from Dragon Warrior—I've never played anything in the Dragon Quest series. I just happen to like dragons

Hi and welcome to Omnimaga!

I was taking a peek at the benchmarking test you wrote. I wrote something a little more optimized (size and speed) for the 84+ benchmark.

Code: [Select]

:1
:For(A,1,2499
:tan(tan-1(e^(ln(√(Ans*Ans
:Ans+1
:End

It ran in ~2:22.47 and resulted in 2.499.999992
I took another look and realized I could improve it a bit by merging two lines into this:

Code: [Select]

:1
:For(A,1,2499
:1+tan(tan-1(e^(ln(√(Ans*Ans
:End

This completed in 2:18.36 and returned the exact same result. I'm not sure if there is any way to optimize it more since I don't play around with BASIC much anymore.

Welcome to Omnimaga, hope you'll enjoy your stay!
And don't worry, we all started out as calc n00bs at one point

It is fun to try to get a huge performance out of limited hardware, after all.

Also, have some peanuts:

After discussing with Eeems on IRC a bit more about the benchmark, we managed to create an even faster version:

Code: [Select]

:startTmr -> T
:2499.999992 -> A
:While Ans < A
:1+tan(tan-1(e^(ln(√(AnsAns
:End
:Disp checkTmr(T

The Tmr things are merely timer things so that I didn't have to sit with a stopwatch next to it.
It ran in 134 seconds.
