What you want is:
<$ is_number_1(a) ? 1 : 0 $>

And you can nest it also:
<$ is_number_1(a) ? 1 : is_number_2(a) ? 2 : 0 $>
These <$...$> tags print a C++-Expression to the page. The idea, why I made <?
... ? ... ?> is just because sometimes I do not have an else case. And it is
just boaring to print something empty to the page like:
<$ someCondition ? "Hello" : "" $>.
