[unexpected behaviour with gen-combine]

OK, so my error is in assuming that in gen-combine items expressed as a ratio are 'just' numbers, but they are treated as omn lengths.

 

The behaviour with floats is as I had expected. (gen-combine '(1/2 1/4) '(0.333 0.2)) --> ((1/2 0.333) (1/4 0.2))

[unexpected behaviour with gen-combine]

Hi,

 

I've discovered that if I run the following code:

(list
 (gen-combine '(1/2 1/4) '(1/8 1/16))
 (gen-combine '(1/2 1/3) '(1/4 1/5)))

 

the result is:

 

(((1/2 1/8) (1/4 1/16)) ((1/2 1/4) (1/3 1/3 1/3 1/5 1/5 1/5 1/5 1/5)))

 

whilst I was expecting (and the documentation suggests should be the result):

 

(((1/2 1/8) (1/4 1/16)) ((1/2 1/4) (1/3 1/5)))

 

In general any input that is not of the form 1/2^n  (n>1) generates a sequence of the input elements rather than a single instance.

 

Am I misunderstanding the function or is this a bug?

 

Many thanks for any assistance.

 

Pete
