Re: odd and even numbers
Can you please define the problem more precisely ? It seems to me there are 3 possible answers to come out from any solution (or maybe more) 1 -- odd 2 -- even 2.5 -- neither odd nor even (or, if you prefer, not whole) AFAICS, all the proposed solutions so far have been incomplete, because they failed to produce neither (i.e. they tested for evenness, so if not even then you'd have to assume it was odd). Perhaps the question should be re-stated as How do you test a whole number to see if it is even or odd? in which case the earlier solutions would be good. -- Alex.

I thought the original question stated the assumption that the number was whole. Normally, one tests to see if a number is an integer by comparing it to its integer part. In LC you just ask if it is an integer. It's interesting how people approach things differently when they're using an interpreted scripting language. For instance, in C, one would never divide by two and then see if the remainder is nonzero, because a divide is a comparatively slow operation; one would use a bitwise AND, since that is typically a single-clock op. But in LC, that difference is swamped by the time spent processing the script. And in C, one would NEVER base the analysis on the printed representation, because that would involve generating the printed representation. I don't know how LC represents things, but I would think that it would represent values by the combination of a numeric representation and a string representation, either one of which (but not both) may be missing, deferring generation until it is needed. If that's the case, just asking for the last character of a number might very well cause the representation to be generated, which would be significantly costlier than doing arithmetic on it. -- Ciao, Paul D.

My question (and attempted re-stating of the original) was intended to make it clear whether wholeness is a valid assumption or is part of the investigation. btw - not trying to pick on Jacque, but even if you assume the value is an integer, then her solution will fail in some cases. Why? Because if you test 2. LC will tell you it is an integer - but although it should be even, it does not finish with any of 02468 ?! function aa p return p (p is an integer) end aa on mouseUp put aa(2.) exit mouseUp Of course, if it is part of the investigation then we can then talk about the exact definition of whole number - it's not as widely agreed or unambiguous as I thought it was.

RE: odd and even numbers
From: Peter W A Wood Mark Waddingham kindly explains how the engine performs arithmetic in this QCC entry - http://quality.runrev.com/show_bug.cgi?id=9349 That page states that arithmetic is done on 64-bit floating-point values, which is what I always assumed, and suggests the possibility of going to decimal in the future. I posted this response: Where decimal arithmetic still fails is when a quotient doesn't have a finite representation. 1/3*3 will always be .9... to whatever precision the decimal arithmetic is done. An alternative is to define an 'epsilon' global property, with a default value of something like 1e-15, which says how close numbers must be in order to be considered equal. Comparing a and b could be done by actually comparing (a-b) to (a+b)*epsilon. Allow the user to set epsilon to anything from zero to, say, 0.1. This works for any two positive numbers; negative numbers would work the same, but have their sense reversed. Numbers could be compared to zero, or to numbers of the opposite sign, by comparing their difference to epsilon. What that page doesn't make explicit is whether even intermediate values in calculations are converted to and from strings. Since many numeric values are never needed in their human-readable form (loop counters being the most obvious example), having a way to deal with binary numbers and decimal numbers interchangeably would be a HUGE win. My suggestion was to represent values as the combination of a number and a string, one of which may be missing and only generated whenever something asks for it. A missing number could be represented as a NaN, and a missing string by a null pointer. -- Ciao, Paul D.
