Re: [Factor-talk] restricting ratio literals

2016-10-26 Thread Jon Harper 
I think there is value in having such in important word (string>number)
have a documented behavior. Right now it's hard to document all the things
that are correctly parsed by this word...

Imho, choose based on what makes the implementation better. If the
parser can be written in a simpler (and probably faster) way by
dropping support for ratios in uncommon bases, then let's do it. Tbh,
I don't think any ratios other than those on the format int1/int2
needs to be supported.

Re: [Factor-talk] restricting ratio literals

2016-10-25 Thread Jon Harper 
I would say no prefix at all for ratios, only base 10.
Also do people in the US consider 1+13/2 a number? Or is it really only
written as 7+1/2?

I think the number literals should only express what people consider as
numbers. They should not replace arbitrary mathematical operations (like
your 60/2.5 example) which are folded by the compiler anyway.

What do you think?

Le 25 oct. 2016 02:22, "John Benediktsson"  a écrit :

Those examples do look ugly -- maybe base 10 ratios only is not a bad idea.


But would it support the 0d prefix?  e.g. ``0d1+1/3``?
