[edit] 'Values' as numbers

Should it be clarified that a value does not need to be a number? —Preceding unsigned comment added by 84.120.151.152 (talk) 14:46, 21 March 2008 (UTC)

[edit] 'Values' as arguments

I am not happy about this stub. To say that 'functions map a set of values to another set of values' does not at all help the reader to understand the conventional distinction between function arguments (input) and function values (output). I strongly suspect that the person who formerly made a redirection to function had this distinction in mind. (By the way, this is the reason why real-valued function refers only to the range, not to the domain.) At the same time, I do recognise that we mathematicians tend to use the same terms in different meanings in different contexts; and 'values' of variables certainly are mentioned. In some common situations (e.g., with existing and non-zero Jacobians), you do not need to distinguish input from output very carefully; and the description supra might be more apt.

I would like to rewrite this in a more 'conventional' manner. Actually, I found the stub while looking for sensible references from an improved version of binary operation; but was disappointed.JoergenB 12:23, 15 September 2006 (UTC)

Go for it! Like I said above, the whole article is more of a "placeholder" than anything else. I am not qualified to write a math article, so why fake it? Dullfig 20:12, 15 September 2006 (UTC)

What does vaule mean

-- I suppose it is a typo for value :-) However, there are problems with this stub (supra).JoergenB 12:23, 15 September 2006 (UTC)
