Hello Jürgen,
After reading your email and the apl.html documentation on ⎕CR
and so, I've have two questions:
1) How does one know B is a rational number? The apl.html
documentation for 26 ⎕CR B does not showthat there is a cell type for
rationals and I could not locate one in the
apl on openbsdopenbsd on rpi
nice to see openbsd shaking off the cobwebs

Hi,
the rational numbers are still quite new, so I would like to wait
a little longer before
making a new release.
Rational numbers cannot become the default because some
computations with them
take considerably more time than their float
Hi Fred,
the existing mechanism is 27 ⎕CR B to get the numerator of
B and 28 ⎕CR to get the denominator > 0
of a quotient or 0 if the number is not a quotient (and then 27
⎕CR is the double B cast to uint64_t.
Unfortunately there was a bug 28 ⎕
Guys,
To make it clear, I'm not asking for bigints. I'm just seeking
to get the maximum benefit of having rational numbers with, as Xtian
says, ~63-bit numerator and denominators. As long as you limit
yourself to using addition, subtraction, multiplication, and division
and avoid overrunn
