Really really fast BASIC handheld
Hallo,
I tried something from which I have never expacted to be much much faster as the HP Prime. And it's using interpreted BASIC on a small handheld: Tada: The New Nintendo 2DS XL (release 2017) with SmileBasic (you can get this like games from the Nintendo Store). It's fast! Very Fast! Example: The Summation Benchmark: CLS M=MAINCNT 'Frames since start of Basic with 60 per second A=0 FOR X=1 TO 100000 A=A+POW(EXP(SIN(ATAN(RAD(X)))),1/3) ' pow is used because 3. Root doesn't exist ' RAD is used to change degree to radian because all trig function use radian NEXT PRINT A PRINT ROUND(10/6*(MAINCNTM))/100; " sec" 'rounded of 2 decimal digits The result: 0.55 secunds, Result 139536.56649434 compare this with the other handhelds like: max = 100000 ~ 7.7s  HWPrime G2 , sum function http://www.hpmuseum.org/forum/thread975...#pid102818 ~ 9s  TI Nspire CX CAS, hardware version N0118AB (2018), OS 4.5.0.1180 (2017): C with Ndless. Post #147 ... This is 14 times faster then the fastest calculator the HP Prime! And with max=1000000 (1 million) you get: 5.53 seconds with 1395587.74219818 And the precision of the calculation is not bad. It's an interpreted program language, which support all feature of the 3DS (like backgrund music, 2 color display with 3d, sprites, aninimation, WIFI, gyroscope, mic, touch screen controls etc.) and all important mathematical functions you need for science. And the RAM for the BASIC is big: more than 8 Megabyte. I have programmed the ULAM spiral (https://en.wikipedia.org/wiki/Ulam_spiral) with changing the starting center and 240 by 240 numbers. The calculation of the first 110000 numbers if they are primes don't need not more than 1 second. And the print of the spiral is done several time per second. If you knew any handheld (NOT PC) with a buildin language and editor let me know please! (No, IDE on an external PC is something like cheating for me. I think that's reason to use a handheld or I can use a PC directly). I hope this will show an alternative way to use existing devices! Bye Bernd
