There is a flag that can be set to prevent that:

    Context("Complex");
Context()->functions->set(
sqrt => {negativeIsComplex => 0},
);


There is a similar flag for log. You may also want to do

    \$context->operators->set(
'^'  => {negativeIsComplex => 0},
'**' => {negativeIsComplex => 0},
);


so that you can't use (-2)^.5 either.
