[little offtop]
Old Microsoft CALC.EXE from Win 3.11 contains an "easter egg" - calculate 3.11-3.1 and see result)).
(It's WIN16 NE-EXE, then doesn't works on 64-bit new OS's, only on 32-bit new Windows).

RSC 1.3 / 1991 & RSC 3.0 / 1993 - it's the best DOS programmers/scientifics resident calculator. More powerful than standard CALC.EXE from Windows.

I'm using (more often) simple DOS resident HEX/DEC calculator CALC.COM (remaked 2005) . But it's for amateurs..

Good functions, but It is sorry that on vbаsiс..
However thanks, - added into collection.

I also use speedcrunch. You can easily switch between using binary/decimal/hexadecimal for output (no restriction on input) and the best thing is it shows the result while you're still typing. It also has a bit level view which also updates on-the-fly.

And here is a specific calculator for calculate offsets in 32-bit PE-EXE file:
File Location Calculator (c)PCL

His little-modified version 1.4.0.4(+) is attached to this message (See attachement).
Added option - displays "<TaiL>" string after section name if (given address > FileOffset+VirtualSize) for this section.

Example of PE-sections table in 32-bit PE-EXE with tails in sections:



See ".text" section for example:
VirtSize =00028874h
PhisSize=00028A00h
Then:
<Tail>Size= PhisSize-VirtSize=018Ch


--Add--

For "Triming tails" of all sections in PE-section table of file
use HIEW32 HEM-Plugin PE_TAILS.HEM.

Best response yet!

Strong recommendation: IPython

Just type iPython in your iTerm or WSL or Konsole and use hex(), lol

Sometimes can be useful AnalogX PCalc.

I would recommend SpeedCrunch. It got syntax just like coding, easy-to-use.

I think, programmer, should write calculator himself
First of all, it is interesting and you can add features, required by your calculation style (e.g. reverse notation, if you love it), second, it is not a very difficult task.

p.s. surely, I wrote my favorite myself, here is list of features, maybe someone will find them useful to implement in their programs:
- almost any number lengths are supported, i.e. 128-bit numbers, 256-bit, etc.
- floating point numbers can be with different mantissa and exponent size, so one can just get 128-bit floating point compatible with IEEE-754, or play with 256-bit floats to see if they will help.
- all bit operations are supported, including popcount and cyclic shift even through carry bit (to emulate CPU instructions), but one can cyclic shift even 256-bit number too
- surely, hex, oct, bin radixes are supported, including limiting representation size, so one can always know how many bytes will be required to represent current number in memory (including floating point format)
- binary complement format is supported, one can change signed and unsigned representation on the fly, this is usefull to check, that e.g. -16=240 in byte types.
- full SNaN, QNaN, machine zero, epsilon, +Inf, -Inf and rounding schemes support for IEEE-754.
- some exotic functionality also presents: e.g. representing floating point number as a continuos fraction, checking for primeness, finding gcd/lcm, etc.

and so on... even if I missed smth required for my work, I just edit sources and add this functionality

p.p.s. not attached here, since calculator is a bit ugly and has no built-in help, and one should remember all its commands.

When most calculators hit an overflow you can depend on this one

Old DOS resident HEX/DEC calculator, remake of CALC.COM (c)D.Gurtyak,1990:
CALC.COM v.0.000a, remake 2005

Old DOS resident scientific calculator with reverse notation and minimum of memory requirements:
SCALC.COM v.1.0(fixed) (c)Safonenkov,1992

Both written on ASM.
