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

Can't print "text" .

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.
