i48

i48i48 is an emulator for the HP48GX calculator, so the next time you’re out and about and need to do some quick matrix calculations or work out the integral of a function, just whip out your iPhone (or iPod touch) and have at it.

i48 is based on the x48 project and as such is open source.  The source can be accessed via github here.

Available on the iPhone App Store

  • White screen instead of number area. I deleted the app an re-installed. Now it runs fine. Thank you.

  • There is a solution to that bug. If you press each of the buttons starting at the top right corner moving to the left, then down a row and to the right and so on the emulation comes good. I’ve been unable to track down the cause of this problem as it is in the underlying emulator the i48 uses. I need to get some time to really look into it one of these days 😉

  • When the π button is pushed, 3.1415926536 should come up and not ‘π’. I’ve not found anything else , but will let you know if I do.

  • This is the way the HP48 works. If you want the numeric value of pi then you need to use the ->NUM function (Shift EVAL)

  • Have it on the screen , ” recover memory” yes or no, that’s it. Nothing works

  • Just like in the real HP48 you need to press the button under the “NO” option the first time you turn it on.
