Because vala doesn't support double in generics (the error you got).
Not sure if it would help, but did you try its suggestion to use
'double?' instead?
This is an implementation detail but int is easier because of
G_[U]INT_{TO,FROM}_POINTER which can be used to convert from int to
pointer and back. (and no such thing exist for floats).
anyway, since double is a value type, double? it may work.
