in algorithm section if x == 0.0 then doesnt compile

[yadaniel]

{{{if x >= 1 and x<=1 then     BUG, == should compile here

x:=0; x := -1*computeAdder(x=3, y=x);

end if;
if (x > 10) then

x := 1;

else

x := x + 1;

end if;}}}

Is this algorithm section in a function or in a model?

Check the Modelica specification why the

or <> comparison between reals discouraged:

​\\|http://www.modelica.org/documents/ModelicaSpec30.pdf
Section 3.5, Page 18, bullet 5.

In relations of the form v1 == v2 or v1 <> v2, v1 or v2 shall, unless used in a function, not be a subtype of Real.

The reason for this rule is that relations with Real arguments are transformed to state events (see Events, Section 8.5) and this transformation becomes unnecessarily complicated for the == and <> relational operators (e.g. two crossing functions instead of one crossing function needed, epsilon strategy needed even at event instants). Furthermore, testing on equality of Real variables is questionable on machines where the number length in registers is different to number length in main memory.

This is not a bug. Check the Modelica Specification. Comparison between
reals using == or <> is discouraged.
