I need context for the following strings:

#: ../gtksourceview/language-specs/cg.lang.h:3
#: ../gtksourceview/language-specs/erlang.lang.h:3
#: ../gtksourceview/language-specs/ruby.lang.h:4
msgid "Builtin"

#: ../gtksourceview/language-specs/css.lang.h:4
#: ../gtksourceview/language-specs/fcl.lang.h:3
#: ../gtksourceview/language-specs/fortran.lang.h:4
#: ../gtksourceview/language-specs/gap.lang.h:3
#: ../gtksourceview/language-specs/gtkrc.lang.h:4
#: ../gtksourceview/language-specs/haskell.lang.h:4
#: ../gtksourceview/language-specs/ini.lang.h:5
#: ../gtksourceview/language-specs/octave.lang.h:4
#: ../gtksourceview/language-specs/pascal.lang.h:3
#: ../gtksourceview/language-specs/sql.lang.h:3
msgid "Decimal"

#: ../gtksourceview/language-specs/fcl.lang.h:8
#: ../gtksourceview/language-specs/gap.lang.h:7
#: ../gtksourceview/language-specs/octave.lang.h:10
#: ../gtksourceview/language-specs/R.lang.h:9
msgid "Scientific"

#: ../gtksourceview/language-specs/java.lang.h:8
#: ../gtksourceview/language-specs/ooc.lang.h:8
msgid "External"

#: ../gtksourceview/language-specs/po.lang.h:7
msgid "Special"

In some languages it could be either a male gender, a female or a neutral element.
