Re: 43S News

There are various other functions on the CPX menu that could be changed to work on non-complex types too. What shall this function do then? What "various other functions"...

Re: 43S News

I don't know about the rest of the world, but there is also "Czech notation" which is like American/English notation but replaces square brackets with angle brackets. I learnt <-π, π] (in Norway). So that's four different notations so far. ISO 80000-2 only lists the (] and ]] styles (hooky scanned ...

Re: 43S News

You might also see it written as: ]-π, π], but I think (-π, π] is the more common style. Not where I learned maths :) I always learned it as ]-π, π] and had never seen (-π, π] until this discussion cropped up. I find the former notation more intuitive and indicative of its meaning. I think "]-π, π]...

Re: 43S News

ϑ ∈ (-π, π] is equivalent to -π < ϑ ≤ π. Thank you for explaining. I never knew. You might also see it written as: ]-π, π], but I think (-π, π] is the more common style. The round bracket (parenthesis), or reversed square bracket means the value given at that end of the range is excluded from the i...

Re: 43S News

5. Well, the names are similar. Thus, if you spend a prefix key [HYP] then it's a no-brainer to combine it with the trig keys. But that's all. If, however, the public would be roaring for the hyperbolics going into TRI , I might do though frowning... In a way, the normal trig functions are also exp...

Re: Benchmark Speed?

Is that a typo in your MATH benchmark data, or is the 32-bit Windows build, running in a VM, really five times faster than the 64-bit Linux build, running on the metal on the same machine? :shock: I have a Ryzen 7 2600 in the Office with native Windows 10. Tomorrow I can check Free42Windows decimal...

Re: DM42- clock losing time

I'm pretty sure the last time I set mine was sometime on 31st March (when the clocks went forward in the EU), and it is currently running 86 seconds fast after 43 days, so that's about 2 seconds per day in my case.

Re: Hello World!

Does Swiss Micros sell any apparel? You could always buy a bunch of calculators and make scale mail out of them. (emphases added) Ough, thanks to Linguee for finding this term - Merriam-Webster doesn't know it. Nice proposal anyway. 8-) M-W seems to call it scale armor . Calculator armour would be ...

Re: External stack

To clarify how LSTO works under the hood: it creates a variable just like STO, except the variable is tagged with the current RTN level, so when a RTN is executed, it can scan the list of variables and delete all the ones with the current level. Just to clarify something, by "RTN", do you mean any ...
