CalcTape masters the four basic arithmetical operations, exponentials, and percentage calculations. Do similar calculations and play different scenarios. Use your existing CalcTape files as templates. CalcTape will refresh the whole calculation automatically again and again. Open the files later and you can change the calculations. Comment your calculation terms, to give sense and context to it. Use intermediate results to check and structure your calculation. Change any term afterwards and CalcTape will refresh the whole calculation automatically. Enter many calculation terms in one turn and still keep an overview - like on an adding machine. CalcTape makes the arithmetic process visible - you can generate intermediate results and subsequently correct or change all numbers and operations. With CalcTape, also extensive calculations remain clearly structured. But then, I'm a bit weird.CalcTape is a revolutionary new kind of pocket calculator. Personally, I think it's worth every cent. How many days to Christmas? - today as whole days) What's $15 in euro? ($15 as euro) How many centimetres in 12 fathoms? (12 fathoms as cm)Īnd the developer is still tinkering with it, and that $15 is a lifetime license. The restricted space and keyboard facilities apply again, so it makes sense.įor me, Opalcalc sits nicely between the input complexity of the calculator (infix or postfix? Do I start with a number and apply a trig function to it, or start with the function as if I were writing the formula on paper? How do I get at the stats functions again?) and the big iron of the fullblown spreadsheet, and it needs me to have a full-size keyboard I can use with it without having to grope for symbols.Īnd some of the things it can do would need Google, otherwise. I tried a couple of the wabbitemu TI emulations and was thoroughly impressed with the quality of them - and I completely get that a smartphone host for one of them would be a good idea. But the traditional calculator, however good they are (and my experiences of the things goes back to the 1970s and I still own several) is specifically designed to be finger-friendly in a relatively restricted space - something that computerised calculator programs don't, it seems to me, need to emulate. I rarely evangelise - I am told often enough that my taste in software is "a bit weird" that I certainly wouldn't want to insist that a particular thing is best. I reckon they were probably a more visually stimulating and fun design for kids. They get their power from ambient light and have an LCD display, but I would have preferred the older - now obsolete - battery-driven versions which had a red LED display. They were very difficult to locate, but I finally managed to source them from nearby Australia. So, I haven't bought a calculator in years, though I did buy two of the superb Texas Instruments "Little Professor" educational math drilling calculators a couple of years back. I have given most of the the rest to a local charity mission shop that I regularly take stuff to (from dumpster diving and people giving things to me as they know I collect for charity). I kept 2 of the fx type for when my daughter would need them, and now she does, and today it transpired that she seems to have already "misplaced" one of them, so is using the 2nd as a backup. Being a collector (and constructor) of calculators from way back, I had already acquired an assortment of several good used ones (discarded/free), which I cleaned up and overhauled and got working tickety-boo. I empathise with you regarding the ability of schoolchildren to lose their new school calculators. However, Wabbitemu is now on my list as I downloaded and installed it just Thanks for the link to Wabbitemu. : I didn't consider (or claim) my list to be comprehensive at all.
