Revision 5130 - (view) (download) (as text) (annotate) - [select for diffs]
Modified Mon Jul 9 12:45:06 2007 UTC (12 years, 7 months ago) by dpvc
File length: 2371 byte(s)
Diff to previous 4994
Added new flags to error checking of operands and function arguments.
This is so that a context can be developed that is more forgiving
about what can be put next to what.  Such a context can NOT be used
for evaluation or answer checking, but can be used to generate TeX
output in more sophisticated situations.

Update to handle the fact that the Value package now includes the
context with all MathObjects.  (This may still need some work.)

Add a new operator // to be the same as / except its TeX form is a/b
rather than \frac{a}{b}.  This makes it possible get horizontal
fractions in exponents, for example, where vertical fractions often
don't look so good.

Eliminated unneeded parentheses in TeX output when unary minus and
plus are used with fractions.

File length: 2140 byte(s)
Diff to previous 2696
Added flags that control the reductions performed by
Formula()->reduce.  Each reduction operation can be individually
enabled or disabled in the context, and in the reduce() call itself.

More complex reductions need to be developed.

File length: 1880 byte(s)
Diff to previous 2681
Improved TeX and string output in a number of situations.  Improved
use of parentheses to avoid things like x+-3.  Fixed wrong parentheses
in powers.  Display (sin(x))^2 as sin^2(x) in TeX output.

TeX mode now adds parentheses around fractions, when needed.
