Is there a way to choose the colours? If using it with 'implicitplot' on something like y - x it gives brute red and yellow ...

For each of the definitions

p := proc( x :: float ) :: float; x^(2/3) end proc:
p := proc( x :: float ) :: float; x^evalf((2/3)) end proc:

i get an error by calling Compiler:-Compile( p ):

"Error, (in printtab[CodeGeneration:-Names:-Rational])
rational numbers and arithmetic are not yet supported"

Any suggestions what to do (except manually converting
all exponents to floats)?

Edited to add: for example the following does not work:

c := proc (S::float,...

Why Maple 11 does not reply by true for the following snipped:

assume(m::real):
PIECEWISE([exp(m)-exp(-m), m <= 0],[0, 0 < m]) = min(0, exp(m)-exp(-m));
convert(%,piecewise,m);
is(%);

It handles the 3 cases 0<m, m=0, 0<m correctly. I find that strange.

Given an expression is there a easy way to convert occurrencies of diff, int, limit, product, sum to their intert forms? For diff one can use convert(%,D), but for int and sum it is not the right way. Are there other ways instead of using "subs(sum=Sum,%)" etc ?

I observe that within graphics numbers are displayed according to local settings (so 0,001 stands for 1/1000) - no problem for me, but annoying, actual output displays with a point as decimal separator. For pretty display I sometimes use something as 'eval(expr, x=1)': '%'=% which works fine in mws, but in mw it displays the eval statement - is there a workaround for both kinds of sheets? And saving a mws as mw does not respect the font size for 2D output (it changes mine from 10 to 12 (and behaves odd, it always uses italics, but we had that already i think). (Win XP home SP2,
