Some strange behavior:

(set 'lst '("23" "hello" "3.14"))
(float (lst 1))
; -> "3.14" instead of nil

Why so?

Code: Select all

newLISP v.10.3.2 64-bit on OSX IPv4/6 UTF-8, execute 'newlisp -h' for more info.

> (set 'lst '("23" "hello" "3.14"))
("23" "hello" "3.14")

nil

and

Code: Select all

newLISP v.10.4.4 on OSX IPv4/6 UTF-8 libffi, execute 'newlisp -h' for more info.

> (set 'lst '("23" "hello" "3.14"))
("23" "hello" "3.14")
> (float (lst 1))
"3.14"

indicate some kind of regression over the last year. I haven't got the intermediate versions here to test when this happened...

I get the same thing on 10.4.1. But note that (lst 1) returns "hello", as expected.

Code: Select all

newLISP v.10.4.1 on Win32 IPv4/6 libffi, execute 'newlisp -h' for more info.

> (set 'lst '("23" "hello" "3.14"))
("23" "hello" "3.14")
> (float (lst 1))
"3.14"
> (lst 1)
"hello"

Good catch, denis.

Same issue on my Linux desktop.

Code: Select all

newLISP v.10.4.3 on Linux IPv4/6 UTF-8 libffi, execute 'newlisp -h' for more info.
> (set 'lst '("23" "hello" "3.14"))
("23" "hello" "3.14")
> (float (lst 1))
"3.14"

This is a bug in the 'float' function when using it on list elements, introduced in a development release before 10.4.0 and is fixed now in 10.4.5 in progress:

I will do a maintenance release as soon as I am back in the US next week, probably on the 15th of November.
