- 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,

- 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
- 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!
