[Amforth] d>s in amforth (double number > single number)

[<f.z...@me...>]

In gforth the word d>s (It couverts a signed double drecision number to a signed single precision number) is part of the default word set.
This word is not available in the default amforth word set.

Can't find a amforth word definition of s>d. 😞
I would very much appreciate when somebody is able to provide the amforth code. 


BTW: I LOVE amforth!


Groet!

Fred

d>s is simple: DROP since the higher cell shall be 0 for this, you
may want to make sure and throw an exception otherwise, a task
that I happily leave to the reader ;)

It's in the file common/words/s_to_d.asm. The definition
itself is short, but somewhat surprising

: s>d dup 0< ;

Hello Fred,


> The word s>d is in the common/words/ folder but d>s ins't :-(

: d>s ( d -- s ) drop ;

Assuming that the high number (2 Bytes) resides on top-of-stack, the low
number below that.

Cheers,
Erich
