Purpose of use

Write codes for others to use to illustrate theory

Comment/Request

It would be good to include comments in the Answer section. Is there a way to "print" alphameric characters as comments in the output of long expressions? Of course comments are possible within the expressions themselves.

Bug report

With the Expression field =

9.9999999999999999999999999999999999999999999999999999999E+32767^(1/2)

the Mode drop down = "Real Deg", the Digit drop down = "54", the Answer drop down = "Exponent", the "Accuracy" box checked and the Editor drop down = "Ace", the Answer field is "Error". Answer should be 1.E+16384 (which is the Answer given if the Digit drop down is < "54"). Thank you for providing your website free of charge and w/o adds.

Thank you for your advice.
We've fixed it.

Purpose of use

Theory validation

Comment/Request

Great in so many ways. Suggested improvement: in Keisan CTRL-Z cancels entire Expression field without an Oops function to restore it; code can be lost. But in most systems CTRL-Z reconstitutes the previous state of an expression, so it's easy as a habit to make the mistake of using it in Keisan. Not good!
