[1]  2022/01/16 22:49   Under 20 years old / High-school/ University/ Grad student / Very /
Purpose of use
Calculations in relativity theory which usually deal with big numbers.
[2]  2022/01/10 21:41   60 years old level or over / A teacher / A researcher / Very /
Purpose of use
Serves me well as a programmable calculator for investigations in mathematics, physics and engineering with up to 100 significant digits.
Comment/Request
Dear staff:

Is it possible to print "text" for documenting or commenting on calculation results ?

I have tried to print text or labels or variable names using the println() function - but without success.

One idea was to try the syntax: println("Text"); or using single quotes: println('Text'); which gave me error messages in both cases.

All the best,
Gudlaugur Kristinn

Purpose of use
High-precision calculation of rapidities (hyperbolic angles) in special relativity. Manipulating hyperbolic trigonometric functions.
Comment/Request
I greatly appreciate the accuracy and flexibility of this calculator. It's very nice that I can use variables and nest functions, and the functions never seem to completely "zero out" due to a failure of precision like most calculators that are available for calculating hyperbolic trig functions. Especially since I am working with special relativity, where almost every single "daily life"-scale velocity is unbelievably small compared to the speed of light, so I am usually working with fractions on the order of a few billionths or smaller.

Purpose of use
comparing to javascript calculator
[7]  2021/10/29 09:49   50 years old level / An engineer / Very /
Purpose of use
Identifying issues in converting 64-bit floating point numbers to and from 128x128-bit fixed point numbers and developing strategies to mitigate them.

Purpose of use
Fourier Transform
[9]  2021/10/08 05:08   40 years old level / An engineer / Very /
Purpose of use
Solving problem 751 of project Euler. Google Sheets precision was not enough and I was wanted to see if I could solve the problem without using C/C++ libraries. It worked!
[10]  2021/10/01 20:39   20 years old level / An engineer / Very /
Purpose of use
Calculating the chance of getting the same hash key for encrypting of certain data
