[Maxima-discuss] %and is not an infix operator

[Jinsong Z. <js...@ye...>]

Hi there,

? simp_inequality gives the following example code:

          (%i1) simp_inequality((x > minf) %and (x < 0));
          (%o1) (x>1) %and (x<1)

However, I run it in Maxima 43.0, it gave:

(%i2) simp_inequality((x > minf) %and (x < 0));

incorrect syntax: %and is not an infix operator
ity((x > minf) %and
                   ^
And the help page gives:

           (%i2) assume(x > 0)$

           (%i3) simp_inequality(x > 0);
           (%o3)                         x > 0

I got:
(%i2) assume(x > 0)$

(%i3) simp_inequality(x > 0);
(%o3)                       simp_inequality(x > 0)

I don't know what are the correct ones. Any hints? Thanks!

Best,
Jinsong
