Sample code:

[#ftl]
[#assign testlist=[0, 1, -1, 0.5, 1.5, -0.5, -1.5, 0.25, -0.25, 1.75, -1.75] /]
[#list testlist as result]
${result} ?floor=${result?floor}
${result} ?ceiling=${result?ceiling}
${result} ?round=${result?round}
[/#list]

is causing parse errors in eclipse, because plugin is using freemarker 2.3.8. These functions are in Freemarker from version 2.3.13 (http://freemarker.sourceforge.net/docs/ref_builtins_number.html#ref_builtin_rounding).

I have tried to add new freemarker library to plugin directory and change Bundle-ClassPath in META-INF/MANIFEST.MF, but it didn't work.
