integer to float

[newdep]

Hello Lutz,



Its it possible to extend Newlisp with an option in + - / * ... to

return not only integers but also autodetect i.e. floats.. and round

in float format? Currently an extra function is needed that does a

pack/unpack for float.



An examples on how i thought it could be done for float is i.e. to

add an "f" at the end of float numbers. But ofcaurse more elegant would

be an autodetect... (btw i know mul, add...  exist ;-)



; a float

>(- 1000.54f 100.31f )

900.23



; a float/double

>(+ 1000.123456789123456 1.1234567789123456)



Or if someting like this would work it would be nice too ->



(float (- 123.34 35.123))





Regards,

Norman.

Just do at the beginning or in init.lsp:



(constant '+ add)

(constant '- sub)

(constant '* mul)

(constant '/ div)



Now +,-,*,/ will work on floats and integers alike. This is also described in the manual in the 'Customization, localization and UTF-8' chapter.
